Good first game, could use some indication of damage being done. A screen wiggle, a sound effect, a flash, a knockback, a damage number popup that fades, something.
I was planning to add all of them except the flash and the damage number that pops and I wanted to add a health bar for each boss, But - unfortunately- the time didn't save me and I made it in 5 days instead of 10 because I had another work to do.
