This was a nice, simple, mostly solid entry. I say mostly because while the RNG certainly shakes things up and makes playthroughs unique, I think my 3 runs were a bit too unique. In my first two attempts I never found a single upgrade item so I could die in a couple hits. And then in my third I found so many upgrades I was one hitting enemies even by the third section. Overall I think the procgen is mostly good, it just needs a balancing pass.
Other than that, I think the lack of sound is a bit disappointing because I could easily see this having some nice sound effects for the combat and enemies.
On the positive side, the visuals are great! All the monsters look unique and interesting and stand out from the environment. The level exits are obvious, and the maps aren't too labyrinthine. I also appreciate being able to move continuously!
Good work!
