Thanks for your feedback!!! Probably too many mechanics for 48 hours, I think it hurt the level design, I had to cut stuff (I wanted some more shooty levels).
A swing mechanic could be cool. The idea of Mod-O-Bot is that his parts would be modular, so each limb could be switched out and reconfigured.
I didn't get to fully realize the idea for the jam (I wanted to revert back to ball mode and then build him up again in a different order, like grapple first, then shoot, then legs, or something like that).
So if we add a swing, we could have one arm swing, and 1 arm grapple, then have swingy grapple areas! I also had ideas for wheels for feet, rockets for feet, arms that can pick stuff up, grab and throw enemies, different gun arms, etc
