The use of the limitation was very, VERY creative. That's something I wasn't going into this jam. And the fact that you can leave messages was also really interesting. Sadly, like what others have mentioned, the game doesn't really work too well. Like what KandiStar said, making "escape" the pause and inventory key means that every time I wanted to use the inventory, it kicked me out of fullscreen, which was really annoying. But if you can sort out all that stuff I bet this game could be even cooler than it already is.
Overall, good game that could be better.
If you have some time I would really appreciate it if you could check out my game as well :D
