The platforming was good. The art gave it a simplistic style.
The movement from left-right felt a bit hard to be precise. Often causing me to die. Some audio would have been nice to listen to as I killed the minions. Giving some objective or making it clear that you need to collect some items to advance would have been helpful. I thought I was stuck in the second level. The game is unforgiving, if you die you restart.
Overall, a nice game.
