Nice work! The dash mechanic felt very nice, and I liked that the level design opened up a bit more after the first few linear vertical corridors. Adding more varied enemy designs as you go might make this even better.
Yeah I had a lot I wanted to add to this game (more enemies, abilities, etc.) but time wasn't on our side unfortunately. And the levels go on infinitely (generated infinitely from select 5 rooms (from which I wanted to add more)). Glad you liked it!
