Thank you, there's some really valuable feedback, I'll address some points.
- that "crash", was it the windows overlay with program stopped responding or just instant quit? B on controller was bound to Esc by default which simply closes the game, I don't own a controller so didn't think about it early. I made a quick build with controller support (https://my.mixtape.moe/wtkiro.zip), could you just check if it works at all? Bumpers for slash and shoot, A for jump.
- the inertia is necessary to make it impossible to climb walls, I don't want them to be climbable.
- I'll admit the game is pretty demanding, I want it to be but no pixel perfect jumps so I'll adjust some levels, I want to keep what you called puzzle aspect as well of figuring out what to do and in what order
- The tutorial text appears when you actually need it, you can use some abilities earlier as you did but you don't need them to complete the level
- https://my.mixtape.moe/kolxtw.mp4 I recorded a quick run, there are some areas where you thought extreme precision was needed or you thought you were stuck like that level with walljump tutorial text (look at that part in my run), I'll try to make the design more clear but this was also the puzzle part so I want to keep the figuring out what to actually do and make it clearer when you are trying to do something in a way that's impossible. I guess it will vary between people too, take a look at https://www.twitch.tv/videos/262780391?t=03h42m55s , he figured out the levels you were stuck on faster and beat the whole demo, still I want to make the game a bit more accessible so feedback from you who played worse was more valuable
