hi! i´ve played your game a few times and today i wanted to make a day of "betatester gaming" so ive been messing up a little with the mechanics and i managed to bug the jetpack by upgrading it a lot(tried a few times and it always happens) So when i jumped and started flying the player will never falls until you stop pressing the fly button. When you´ve been flying a few minutes the music starts to lag a bit but the real problem is that if u stopped and fall,the camera wont be able to follow the player and the game will break . Maybe lowering the fall acceleration would make the problem dissapear but i let that up to you. I loved this game and it have helped me a lot to understand a few mechanics that i wanted to use in my own projects so thanks and i hope you the better ( sorry for my english D:)
