Awesome project for a solo dev. I liked your pixel art. The tilesets and other assets were really nice. The grenade is great, but maybe too great! There wasn't much reason to use the other attack when I could oneshot the enemies with a grenade and I had unlimited access to them. The music was nice, but did get repetitive over five floors.
Some quick suggestions if you update the game:
- An audible cue when you take damage. The flash is nice, but audio to reinforce it would help inform the player.
- The attack animation is nice, but a smear frame would really make it feel like it hits harder, and I would increase the hitbox on the attack. Make me want to use it. Slynyrd covers how great smear frames can be in selling motion here: https://www.slynyrd.com/blog/2018/9/8/pixelblog-9-melee-attacks
- More movement on the enemies. I was able to drive by grenade most of them because they wouldn't move.
Overall though, I thought this was a great solo dev jam game and I enjoyed my time with it. Good work.
