This clock setting looks sick! This is a well-executed concept, makes you feel like youre building mini rube goldberg machines. For a game jam, this is a good presentation of a puzzle design. If you work on it further, you can definitely afford to be a little harsher with the difficulty, but that's just my opinion. I do want to mention that it can be a little hard to see the game pieces, especially for those with weaker sight. A lot of the colors kind of mesh and theres not really a distinct outline, so it can be hard to catch everything without paying super close attention. Also, the camera slightly following the cursor can be a bit disorienting at times. Those visual tweaks are simple things tho, and you've nailed what matters most which is the core gameplay. Great submission!
(I was trying level 11 for so long before I noticed the bug update comment LOL. Hopefully, I can see level 12 after the jam period)
