This game has a lot of potential I think, it's basically a roguelike with the exact same layout of the level each time.
I enjoyed the hyperspeed dashing (sliding?) across the floor, and you managed to make hitting the enemies quite satisfying too. The art was also good, I liked it a lot.
I didn't understand the mechanics fully however. Outside the first encounter with the charger, I found little reason to engage in the encounters with enemies, and rather jumped over them to save time. I also didn't understand why I sometimes lost without my time running out, because I didn't see a health indicator anywhere or whatever? On the third floor you are able to fall out of the map (intentionally?) and there is no death plane, so you have to wait until the timer runs out.
Great job either way!
