Very fun game. I think the swinging mechanic could use a little polishing that results in giving the player more control. Often, I would not be able to enter small gaps because the rope was too long. If the player had more control, you could provide a higher skill ceiling and have much harder sections. (I’d suggest looking into the rope mechanics of Worms Armageddon.) However, the concept is great. I see potential for challenge-gameplay or speedruns.
Unfortunately, I suck at this game, so I didn’t manage to collect all four of those things. Made it to the end, though. Had fun. Great game.
