This game definitely has a "Klik'n Play" vibe to it and I mean that in the best way possible. I like that it doesn't take itself seriously. The box-carrying animation is adorable and by the end those boxes felt a bit like the Companion Cube in Portal. I also appreciate you can play with the map open and with a gamepad!
There is definitely some jankiness to it. For one, the music stopped playing at some point (though it was becoming repetitive, so I didn't mind too much). The worst for me was the double jump being super finicky. I couldn't pull it off reliably. I'm also not quite sure how to dash? I'm not even sure I ever used this ability? Avoiding the bullets at the end of the boss fight felt impossible, but thankfully he got stuck in a loop and I could shoot him many times in a row and win.
I think what I enjoyed the most were the surprises. There were multiple instances of the game staging something weird and surprising, which was delightful.
Good job! :)
