I really liked it, the Atari vibe was very good, the concept of the game too, a good implementation of a short metroidvania, with powerups that change the gameplay. but the movement wasn't that good, I missed a "coyote time" in the jump, and when I picked up the glider it became more difficult to control. In the flying part, I got stuck in the two parallel spikes and couldn't get through. Overall it's a very good game, a little more polishing will be perfect.
