The base idea is good and the artstyle and music go very well together.
However I fail to see how it qualifies as a roguelike, it misses the most important part of roguelike games : procedural generation (except for the powerups maybe ?). The waves of enemies, their patterns and numbers could have been renadomly generated to qualify as a roguelike, but for now I don’t see it too much.
And the third wave is incredibly difficult, even by dashing out it is almost impossible to survive, and a bug in the game makes the 2nd wave not spawn when we play a new match, so we have to restart the game completely.
