The plan was originally that there would be some kind of rating system. So if you pass the level you get 1 star, if you do it in under x loops you get 2 and if you do it in under y loops you get 3 stars. I had stuff to do on Sunday so I didn't have time to add that before the deadline but that was the plan. I think that's better than a max number of loops because even people like my parents who have never touched video games can make it to the end, but I do agree that without something pushing players to do it in less loops the game feels incomplete.
The graphics are not something I'm proud of but I'm not very good at presentation yet, and wanted something that was a bit more than just shapes and colours. I also thought it would be funny to contrast a morbid name like "Climbing on Corpses" with a very goofy cartoony aesthetic.
Anyway, thank you so much for your feedback!
