Thanks for doing such a great feedback !
I'm glad you enjoyed the game and the references :D
Concerning the improvements, we planned on doing a "door" for the exit but felt like it was out of place, maybe we'll end up adding one in the future tho, and on top of that I presume that you didn't played the game in fullscreen considering there is only one tile hole per level when fullscreen is active :D
And don't worry, we planned on adding more levels in the future, we already made some improvements that will be released at the end of this jam voting period !
