It's a very cool concept but, it doesn't feel like you're using the concept as much as you could, since there's no need nor benefict from keeping the conections. I would suggest adding a slow reload to the bullets and that the beam "evolves" like the attack from Yuri on Awesomenauts.
I loved building the dungeon, I died on level 4 and realising I had to start doing 3 enemy rooms-1 heal room was kinda scary heheheh.

The most powerful mechanic is the dungeon creation. I tried to implement the jam's theme not only in the creation part, but also in the general combat system. I understand that the combat system did not become as strong as the dungeon creation. For a full-fledged game, i'll probably redesign the entire combat system from scratch. Your ideas are taken into consideration. Thank you very much for your feedback.
