OMG dang bro you did a great job on this! At first I was like oh cool, then I found the chests and was like ooo you did a good job then I found the Speed upgrade and was like WHAT ELSE IS THERE!?!?! Then I found the Giant Chest and was loke woah!!!! very good game my dude if you added a leader-board system then that would take this to a whole other level and add in a multiplayer mode and more upgrades you could slap this baby down in a store and make some money! (My high score is 2723 btw)
