It was a good submission! It had fun visuals and gameplay. The only problem is you may have made it too hard. If you continue this project some playtesting would do this game some good!
Thanks for playing! Sorry you found it too hard. I think level 5 is the limit definitely. I managed 4:23 to complete the game, but does take some practice to get used to controlling the rocket, and also work out when to get planets out of the way. Cheers!
