no linux build D:
i love the art style and it's very juicy! though it could use some subtle screenshake
i can't actually type commands, sadge
i think the default aiming mode should be mouse, the arcade mode constantly misses because it doesn't shoot ahead of the enemies
you also shouldn't make the players manually pick the tutorial, because most don't (i sure didn't, which is why i played my first playthrough without parrying at all haha). and wall of text tutorials usually don't work great, they're hard to remember and interactive tutorials are much better at teaching
the ui is a bit confusing, i had no idea where my health was until i did a couple of runs
it's pretty unclear when you hit the parry and when you miss, the little knockback makes it look like you did get hit
the difficulty is also pretty brutal, the player's projectiles are small and don't travel that fast, you only heal 1 health per round which is way too little, and the first boss is already pretty difficult. i'm not a fan of its telegraphing, i feel like it would be clearer if the laser attack did a little pulse once it's fully charged up and only then actually attacked, the attack where they circle you and shoot one-by-one is nearly impossible to dodge/parry - they stay locked on to you way too well to dodge them by moving and they shoot way too frequently to dodge them by parrying
for being such a core mechanic, the parry is very unforgiving. it would be nice to have some grace, so if you parry a couple of frames too late it still counts, as well as the hurtbox increasing while you're parrying so you can parry attacks further than you would get hit
i also kept forgetting that i had my ultimate ability, it'd be nice to have some sort of indicator
funnily enough, i got the furthest in my very first playthrough where i had no idea you could even parry - i got to the second phase of the second boss, while on the next ones i couldn't even beat the first boss (because of that circling attack, it's just way too hard D:)
tl;dr: it's great and the polish is amazing, but please playtest your game more
