WOW!!!! How does this have 0 comments?? This is one of my favourite entries from this jam. And it's your first ever game??
Just to be sure, you didn't use AI at any point during the development of this game, did you? If you came up with all that by yourselves in 48 hours, this is seriously incredible! Good job!
Also, you could play into the “loop” aspect more by having the clones repeat very short sequences of actions, like going around in a circle, while the player puts boxes to push in its way or something.
If this is your first ever game and you didn't use AI, I highly encourage you to make more games, you have some talent!
edit: i'm stupid, i missed the “no ai” tag
