For some reason, 'G' didn't bring me to the next level, but I had a lot of fun replaying the first level with both weapons. This game seems really polished, and I had a lot of fun. Sometimes it seemed like I would press the jump button and nothing would happen, but besides that, I like the controls. Destroying the terrain is fun, it reminds me of Bro Force, though I don't see what strategic advantage you can set up by destroying the blocks before the enemies start coming. Some of the most fun I've had playing the jam games so far!
