I liked the game, the overall feel was good and gave me kinda old school vibes. Though it was kinda hard to predict the direction of the player once he takes off after jumping on those blue bars. Whereas, the invisible wall bug was pretty cool and btw that I wasn't able to figure out by myself until I saw another comment. At the moment I am at level 3, and haven't completed it yet as I am still trying to figure out how to reach the objective or if there is some hidden bug in the level.
Overall a fun game to play and dunno but for some reason it's visual and atmosphere gives me some sweet old school vibes which I like a lot.
