I liked how the art is very detailed, with all the animations, and also the game mechanics mixing platform with QTE!
This game would be great with a gamepad too ;)
I was pretty confident about my skills for a few minutes, until one QTE finally got me.
One note about that: the fact that QTE are placed completely randomly (it seems), most of the time they end up not blocking the player path. If you want to keep going with this project, maybe you could place them (or some of them) specifically to block the path. Even maybe sometimes forcing on purpose the player to choose between complicated jumps and a QTE?
