I loved playing as a laser worm! It's an interesting dual control scheme, I do wish the tether didn't break as easily when it touched walls. It'd be cool to have a warning system like what you have when they are going too far.
Enjoyed killing enemies with the tether while dodging bullets, it does make for interesting combat.
I understand it's a jam and there wasn't a lot of time for presentation but I'd say this game deserves a post jam graphics update :)
Overall: Good idea, good gameplay execution. Experience would be improved with polish.
