You didn't give yourself any favor taking on three different jams! Still, I think there's some good ideas in that one tight package. It sometimes could feel like a Metroidvania, yet the gameplay is really more basic and simple, which isn't a bad thing. Sadly, I think the plateforming part is kinda weak, and the lack of sound, music or more in depth graphics makes the whole experience really lackluster. But the potential is really here, keep it up!
