Thanks for your feedback!
I'll try to respond to your criticisms:
1) (First boss being drawn out and not fun) Yeah... a bunch of people complained about the first boss's difficulty, which is why I plan to make it easier once the jam is done
2) (One of the first boss's attacks don't end when the boss is hit) Oh which one? I never noticed it.
3) (First boss's bounce attack respite) I'll see what we can come up with as a replacement for the sprite. ( Consider it done now)
4) (Third boss's projectiles not easily visible) I don't see how the projectiles blend in with the background... Though the boss blocking the projectiles is somewhat intentional, but not entirely. I don't think I can really fix that unfortunately without a whole respite of the boss or having the projectiles render on top of the boss, which would look weird when first spawned.
5) (Enemy choreography) Yeah I wanted to do that (and you can see that I did for some of the more deadly attacks), but the animator was really busy so we weren't able to do that unfortunately.
6) (Touhou) Yeah I suck at it too lol, I've only beaten 1 game on normal iirc
7) (Hitbox) The hitbox is 1/4th the width of the entity (this goes for everything), and yes that's where the player stops moving when it overlaps with the mouse. I wanted to have a way to show the hitbox, similar to touhou, but I had no clue how and forgot about it lol.
Thanks for pointing out these criticisms!
