Really simple yet intricate game. I've only played for an hour, but I like it a lot.
Idk if controller play works as intended; it seemed as is the right stick worked as a macro for keyboard inputs and it's set to only 8 way shooting instead of 360° aiming, which felt unintuitive imo (I played with an SN30pro+, so who knows if it's an isolated issue).
I'll play it more and maybe give some more feedback afterwards. Congrats for making such a beautiful game ;)
PD: have you thought of adding bosses every other stage?
