Hi! Thanks for testing our game and for the feedback.
This is actually a critical bug that I only just now. There should be multiple levels but apparently I somehow managed to break the level switching script during the last evening as I'm certain that it has been working previously. In my understanding critical bug fixes are allowed by the jam rules so I have now updated the build to a version in which the player can actually proceed in the game...
Sorry for the trouble, but please try the game again with the new version if you have time! The levels will get even more interesting after the first one!
