This is an AMAZING game, you've put such effort into including as many mechanics as possible. It's most surprising that this was made in 5 days. Creativity is really put into this game, I like it :D
One of the bugs I found is that your checkpoint saves even when you quit, so whenever you replay a game and dies before reaching the checkpoint, you are instantly spawned at that checkpoint, really absurd.
But overall, This is one of my favorite submissions I've played so far!
