What an amazing accomplishment to pull this together in only 14 hours! Glad I read the game page and learned about the rhythm mechanic; I don't recall seeing something like that in a clicker game before. After a while I got so caught up in the flow of pressing buttons to the pulsing beat, I wouldn't realize I had enough money to get an upgrade. I ended up playing through all the unlocks.
"Laser BEEEEAM." :D
Right now it takes too many manual clicks to get to the cool part; your first rhythm weapon. I would have also appreciated some kind of visual cue for the beat to time my presses with.
Well done!
