Thank you so much for playing my game! I'm sorry you ran into some bugs. A few people have mentioned the interaction bug. Usually moving away from the Gameboy and back to it or refreshing solves it. I'm not entirely sure what's causing it just yet. The jump bug is weird, I only found it in testing a couple times towards the end of the jam so I didn't have time to implement a solution unfortunately. As far as the levels, there is only two levels in the game. The tutorial level and the second level. Once you get the second key you beat the game. Thanks again for checking it out and I really appreciate your feedback!
