This game is challenging but I feel like beatable. It even has some speedrunning strats. I enjoyed it.
Unfortunately, there are a few bugs that make it really frustrating to progress. Like when I press E to take an item it "jumps away" from me, as if I put it on the ground. This happens most with long platform. It is also possible to get yourself into positions which you can't get out of.
I think this game is great, just needs a bit of polish.
