I love the concept!
I found the hitboxes of the spikes to be a bit larger than expected and the hitbox of the jump platform to be a bit smaller, which led to some frustrating moments, and I eventually gave up on level 3. I beat the rest though! I didn’t notice the “PLEASE PLAY IN FULL SCREEN” at first, which made level 4 very confusing, but once I could see the flag on the left it was fine :)
I agree with the comment below that the fan is great, and I wish it was needed more.
Top-notch walk cycle, I love how the little guy is stumbling along cluelessly :)
