This is promising.
The gameplay is simple and reminds me of Enter the Gungeon, another roguelike. The color palettes are varied but not an eyesore, the psychadelic backgrounds and portal effects are pretty cool but not distracting in gameplay.
For me, the framerate seemed to drop after playing in a fog of war/dark stage, I use Edge and don't know if that affects the performance poorly. Also, the font is a little hard to read either due to low contrast or the line striking through makes the characters hard to make out.
