I like the idea of the game, and it's fast paced, which is a + for me.
However, the gameplay feels a bit lack-luster. You basically play a platformer with obstacles that sometimes can not be avoided, and you always end in the same level where you have to collect 3 keys.
I think making every obstacle avoidable (except for the first one) and making this underground room a punishment rather than a must do would be a lot cooler.
I like the visuals, no music sadly :( But cool idea! I really like it!
