While I have absolutely fallen in love with the main game, I have felt incredibly frustrated and exhausted as I was finishing Cleanup. I couldn't wait for it to end, actually. I'll try to explain why it felt like such a huge departure from the OG Heavenly Bodies:
1. The tools are so incredibly glitchy. The collisions genuinely feel terrible in this game, and it's most evident in the tools you carry on your belt or attach to your jetpack. My hands constantly, and I mean CONSTANTLY got stuck between my body and the tools on my hips. If you only carry one tool on each hip, it's usually pretty easy to dislodge your arm, but if you were foolish enough to equip two tools on one side, good luck! I've genuinely gotten my arms stuck like this for 2–4 minutes at a time, and have been almost killed by this issue (while actually only carrying one tool on each side!) because I have accidentally decompressed the chamber I was in, and as I was flying out I realized BOTH of my arms managed to get stuck alongside my body, so I couldn't grab onto walls while being throttled out of the space station at a high speed. Additionally, if you have two things attached on one side, good luck trying to grab the one you want! Or grab anything on that side, actually. Because your hands can get stuck not only between your hip and your tool, but also above your bulky tools.
To solve this, please, please make tools non-collideable with your hands only. This way, you can still have those narrow corridors where you have to disconnect your tools to pass through, as your tools would still collide with your torso/legs and make you stuck, but that would solve all the issues I've described above.
Some more collision issues I've personally encountered:

Antenna/receiver tool clipping through the wall of a chamber and flying into outer space. It was not flying at high speed, so I'm genuinely confused about what made it pass through a solid wall. It was in one of those debris chambers, but unfortunately, I don't remember which one.
What made it worse is that because it was moving at a slow speed, it didn't go out of bounds and respawn for a good 5–10 minutes. So I had to go to the communications antenna to see where it was floating, then I tried finding it with my jetpack (failed, because it slowly bounced against something and started moving in some other unpredictable direction), and eventually the tool went out of bounds.
And speaking of tools getting lost, why can't I respawn a tool manually in the tool bay? Why do I have to restart the game for it to happen? Please, add a button that respawns each tool in the tool bay.
I have actually softlocked myself by getting a piece of scrap stuck in the claw machine in the scrapper room. It was the narrow, springy antenna that had to be held in a retracted state by hand to be shoved into the scrapper. I tried folding it with a claw at first, and its dangling base bit (the trapezoid shape) got stuck between the two movable halves of the claw and the base rectangular bit of the claw that moves it around. It couldn't be dislodged with either magnets or brute force, so I had to restart my game and lose 20–30 min of progress.
I believe on day 6 you're meant to go into one of the debris chambers that has those bending/springy white armature bits sticking out. They're meant to prevent you from crawling in with your tools as they get caught on the bars, and, I'm assuming, were meant to bend a bit but still not let you through. Unfortunately, on my first attempt I didn't notice the little crevice to put my tools through on the other side of the challenge and tried crawling with all four tools still attached to me. Even more unfortunately, I did get through. Quite easily and quickly actually, by just pulling myself with my tools with brute force. And tool & armature collisions seriously freaked out, with the bending armature jittering across half of my screen without stopping me at all.
Perhaps, those armature bits can be more solid? You can place them a bit closer together so my body simply can't fit between them with tools attached.

2. Another comment on tools, but a different one: why is on/off and attach/detach the same button? If I recall correctly, the game does not use X on the controller at all, only Y/B/A. Why couldn't on/off be A, and attach/detach be X? This was the most annoying with a magnet gun, as I often want it turned on, and then attached to my jetpack to gather scrap more efficiently. This setup was very finicky to do.
3. The last fundamental issue for me is how samey the game felt throughout. It gradually introduces new puzzle debris chambers and tools, but they really didn't capture my attention, especially the tools. A lot of them are just "bring this tool up to a broken object, hold a button to fix the object".
Drill is just "hold a button to screw bolts back in". Duct tape is "bring up to a hole and move your hand to the right a bit so the hole is taped over". So you just carry 4 of these bulky things on you to do the different flavors of "fixing" while the actions performed by the player are almost identical.
Leak scanner is literally useless, it's used once in the entire game and you can complete the task easily without it. The leaks make a noise, and duct tape is really easy and quick to use over large areas. It was literally more efficient to just hear a noise and go over a large area with a duct tape by moving yourself with one hand and holding up tape with another.
The detonator is not a a tool at all! It's a quest consumable. It doesn't do anything. You just wear it and then attach it to a thing at the end.
I think the game could have been more exciting if the tools were introduced through the puzzle debris chambers, instead of being handed to you. You start your day, go to a puzzle chamber, use older tools to get a new one (e.g. use magnet to dislodge a drill), and then do an introductory puzzle in the same chamber on how to use this new tool (using my primitive example, unscrew some bolts with the drill to get out). Return to your ship and do some repairs using your new gear. After discovering a tool, they would respawn at your space station.
Additionally, I feel like the game didn't have to give you access to the whole space station right away. Instead, each day a new section could have been docked to your station. Right now it just feels long in every direction but ultimately empty. I really feel like it was designed like this so players can struggle while dragging huge parts out of the delivery bay through the whole dang station while the new part catches on every lever and nook it can.
Lastly, the ending was just not satisfying in comparison to the first game. I don't feel like I resolved or figured anything out at all. I kind of just did slow, boring, and frustrating chores for a week.
If you're deciding on if you want the main game or the DLC package, I advise getting just the original Heavenly Bodies. This one was an overall negative experience to me.
