It's definetly in need of balancing, there's a lot of things missing. It's easy to see that you ran out of time on this one. 

BUT the core mechanic is there & it's a good one. Love the Idea. hope you'll keep going on that one. I'd love to give it another go once finished. Good work !

Maybe make the movement speed buff scale linearly, cause after attaching a few, movement becomes impossible to control. Fun game, but maybe could use some sort of "win" condition, and then you restart with harder enemies or weaker buffs (notably the heal) or something.

Really loved  this one and the overall design.

I was confused at first, I didn't have a tutorial but I am not sure there was one. Once I read the comments and figured it out, it was really fun. Neat idea! Whats really missing are sound effects but otherwise great game !

Kinda easy after connecting a heal node, but feels very fun!

Fun game! Might want to add that adding connections costs 100 points to the tutorial. Took me a sec to figure that out.
