Witch Beam does not miss.
Assault Andriod Cactus is my fav bullet hell game of all time, so anything WB makes I will play.
When their follow up game, Unpacking, was announced I was initially disappointed. But once I played it, I understood there was more to it and they were letting their team experiment with different genres.
I knew nothing about Tempopo prior to buying it. I added it to my wish list as soon as it was announced, but never looked more into it to make sure I was going in fresh. It's in the vein of many similar puzzle games, but it has the WB charm.
It slowly builds up different abilities as you play and stacks it's difficulty. It's not an overly difficult game, though I'm not super far into it yet.
Around stage 16/17 (about 30-45 mins in) you really start to see things come together. The timing gets tight and it's very satisfying seeing everything play out once you nail it.
I wouldn't say it's an easy game, but so far it's doable with enough thinking. I'm not good at most puzzle games, so don't be intimidated.
There is a hint system if you hit ESC, but it simply tells you a block needs to go somewhere, not which block or why.
Will update as I play more, but you really can never go wrong with this developer.
