Great
Thought this was a really fun game, only two little complaints.
First off I ran out of upgrades well before I got close to the island, After I got all the upgrades I had a good run and made it about halfway after while but eventualy tipped. This made the game become slightly repetitive (No upgrades left to work for, just doing the same thing except hopefuly better).
Second was the music got a bit repetitive. this was a rather minor problem and I did not even search for a mute button, but still something worth noting imo.
Overall great game.
