Im sorry for the lag, some libraries could be missing or your pc can't handle it. Try running the game another time (some times stops lagging) or try another level. If the lag persists, I suggest you to try the GitHub version, as I compiled it with lower fps (I didn't have time to update the itch build, I'm sorry), in order to be accessible to all computers: https://github.com/OrangoMango/FoodDice/releases/latest Let me now if the lag persists. Thanks.
The jump, as many users told me, is a bit strange, so I will fix it after the jam.
