Wow, you really got a lot done in 3 days!
I liked that you had upgrades and dashes and everything.
I liked the particles when you hit certain things (the vats and spikes and stuff), if you put that on the enemies for blood with would have added a bit more juice to the combat. Actually some enemies did have this (I think, it might have been from projectiles), maybe put that on all of them, and maybe a death explosion 😋
Also when you defeat each boss, it instantly teleports you to the next area and I wasn't sure if I died or if I killed him because he didn't have any health bar either.
Overall though I enjoyed the core gameplay, and I really liked the visuals too! (lots of glowy stuff :D )
