Seriously cozy and fun idea! Whilst there not much to go on here, i could really see it as a fully fledged game. Gave serious poly bridge vibes and the implementation of quick trial and error, plus trails for where cogs went - Very cool!
Ah man I feel the pain hahah - thats always the way with game jams ! I've got a whole page of things I wanted for loop dogg (different songs for instance).
This being your first jam you should be very very proud!
