Feels nice, here's the highlights:
- The boss is a really well done character. The bullets she casts are amazing too.
- The screen space is really well done. Dimensions of what you see, size of battle arena, speed of bullets and boss.
- Animations and sfx: 10/10.
- Intro is amazing: Not too long, but reflects on the gameplay that's following.

However I also saw some problems:
-  My cursor is orange, I love this color. It's basically the default windows 11 cursor with orange color and black outline. That made it really hard to see in the game.
- The game feels very difficult. Almost like you're doing 0 progress. Probably because it doesn't reward you with anything?
- The character you play is boring. It has a constant walk speed and 2 moves. The move with which you shoot is just constantly used and i barely ever used the second slice move. Perhaps make it more dynamic like the boss? Variable walk speed, more moves, etc.

Of course this is the demo, so this is all just me pointing what i see. No harsh feelings, just nice constructive feedback and criticism. Happy developing!
