Brutally honest, just what I like to see!
So I'm 100% with you on the KB&M controls, they're really bad and I should feel bad for implementing them like that. Whenever I work on this again, I'll have to renovate it.
Walking through spikes on ground is intended, but may be deprecated since they were the first object made and the game changed a lot after that.
Good point on the animation, I think it's due some more life than I initially envisioned.
Thanks for spending your time to play my game Tomo
