Thank you! It came out rather simple and basic in just the three hours, I would have really liked to make it more complex with some additional puzzle elements, but them's the brakes.
And yeah, there are a lot of ways to get stuck/trapped in this game by nature of leaving your corpses behind. The R to restart is very necessary. Ideally I'd like the game to automatically recognize when you've trapped yourself and restart automatically (with a message first) but that was certainly not feasible in the three hours so manual player restart had to do.
Thank you for playing! ~
