Is it only me, or is there more games about digging lately :)
I gotta say- I liked this one! The diging felt satisfying! Every hit of the laser, every time the number went up, it had a really nice rythm to it!
The presentation worked well! The pixely underground reminded me of old games like scorched earth. Music fit the gameplay really well.
Upgrades were a nice touch, but I didn't feel that my beam got much more powerful. And since you use the beam 90% of the time I didn't really upgrade anything else.
The theme? Probably the weakest point of a really good game. This was less "everything is a resource" and more "resources are a resource" :)
Over all- if this is your first jam game, I'm looking forward to seeing what you do in the future! Keep it up guys!
