I love the style of this game, and the control mechanism is very cool and fun! The art is awesome, and the sound design is really good as well.
Like others have said, I do wish the game was more forgiving. I got fairly far into it and died to an enemy encounter which ended my whole game. Restarting the whole game was too much for me to bear, so I subsided.
I do also wish the teleport mechanic functioned differently. Having so many different types of teleport in one (i.e. teleporting up, down, to a target, etc.) made it difficult to move exactly the way I wanted to be moving.
