Hey, this was my first jam and it was a great experience! Here's my game -
https://waterveil-games.itch.io/power-supplier
where you collect powercells to keep your defense turret running, and upgrades to help defend against invading robots. I spent the first few hours on a weird idle game sort of concept but ended up pivoting because I didn't think I could make the enemy ai in time, and I'm glad I did because the concept I went with actually lead to some inspiration for my next full game. I had plans to add more upgrades, like a ram for the truck that lets you run over the basic robots or an automatic mode for the turret, but ran out of the time/brain juice needed to make the enemies that would drop them.
Would love any feedback, especially anything that can be improved! Time to go check out this list, also OP your roomba game was one of the first I tried and it was awesome!
