I like this a lot, I get that the jam required you to make the bomb have a 10s cooldown, but I think in the future if you cut it down a bit it would be much more fun, and maybe it could have a larger area of effect, sometimes with the clusters or the moving turrets I'd toss it onto the ground and it'd only hurt one of the four, even though it looked like it should hit all of them, then you're just stuck with the turrets being annoying for 10 seconds.
I'm just being nitpicky though, overall it was an awesome experience and I had fun. Good job!
