As someone that played the original Risk of Rain for over 100 hours and got all the achievements, I can say that the remake's better in every way I can think of. The original game's bug where level collision broke and you just fell through the ground in certain areas is no longer, characters other than Huntress can finally move a little bit while they shoot, MINER IS BACK, and the game's got all sorts of new mechanics and item parity with the sequel.
The pixel art's been redone beautifully, Chanson d'automne... is still the best song ever (Coalescence is still the 2nd best song ever this is the order of it shut up dummy shuyt the u), and the game's levels are exactly as I remembered them (but better). I don't have any frens to play with, but I've heard the multiplayer in this one even works, too.
But if you haven't played Risk of Rain and you want to know what it's like, it's basically like a 2d platformer action roguelike sort of deal where you pick a character from your roster (they've all got unique attacks), take a run as far as it goes, die, and depending on what progression milestones you got in the run, it unlocks new content for future runs. Some of the items interact with each other in wacky, fun ways, as the items in any roguelike should, and all of the characters are unique and fun to learn. You spend your run scampering across the level, picking up items as you go, and looking for a portal that takes you to the next level (difficulty ramps up based on how long your run's gone, so you're encouraged to be quick). There's a bossfight when you activate the portal. The bossfights are ICONIC and COOL, and then it teleports you to the next level (the levels are iconic and cool). At the portal of the second-to-last level, you're given a choice to either move on to the last level and complete the run or loop back to the first level NG+ style. It was all very good in like 2011, but now Risk of Rain RETURNS, and oh man. Oh baby!
What I'm trying to say is that, for what it is, this game's definitely worth paying full-price for (I can't believe this thing is 15USD), and if it's on sale, just get it. Just GRAB IT UP man I LOVE Risk of Rain! I frickin LOVE Risk of Rain, dude! It's got this soundtrack, right? It's the soundtrack, and it's done by this guy called Chris Christodoulou, right? He's got some ABSOLUTE BANGERS, man! You've got to look him up, man! You've gotta play Risk of Rain and then look this guy u
