I feel cloning ability isn't doing anything, as more valuable target in the early game, which is easier, and can cause multiple die from single enemy. In fact, I didn't survive any longer because of this ability...
And the reviving pale toast is somehow hard to locate with effects and enemies all over screen.
Also is the Nuke effect...whether can't kill all enemies, or enemies resown much more fast that sometimes I can't really tell if I use the Nuke or not. Maybe can add some rest time when using the Nuke.
By the way, the art is great, and I like the music too.
