Great rogue like super simple and fun to play. The bonuses are great and really simple to understand after a few rounds of playing.

It feels a bit cluttered once it gets harder. There needs to be more contrast in enemy vs not enemy and player. 

The amount of explosion sprites after a while  slows the game down.  Possibly object pooling them ? It gets chunky when there's tons of particles.

Really enjoyed this I'll be back to play more! I hope you add to this or build something similar! The execution of this idea was fantastic.
