My personal favorite so far.

I couldn't finish before I had to go but I loved this game. Literally everything about this (except the controls threw me off with W being jump) but it was all so good! So much potential as a more fleshed out  puzzle platform, using the checkpoints as puzzle elements to get to locked off place etc. Great job, keep doing what you're doing.

Awesome game! Loved the simple art, the music and the hook mecanic, also really liked the checkpoint implementation. Personally the only flaw on this game is the controllers, JUMP should be another button instead of UP, also put the checkpoint with space bar, not really intuitive, I'm used to jump with space bar so I end up putting the checkpoint instead of jumping. Besides of that I think is game is awesome.

Very fun game! Checkpoint system doesn't quite work, as the optimal strat is to just carry it to the end from start. Could be more fun if dying with a checkpoint brought it back to the other checkopint.
