Thanks for the feedback man. 

Thanks for the info,
sometimes the Arrows disapear, the level should still be playable,
try to reload it and have another go,
You should be able to complete all levels despite some bugs.

Thanks for commenting!

Thanks for the comment about the music btw! I'm completely insured that the composer of the game's soundtrack is very pleased with this!

Thanks,
we tried to keep it simple and only made one controller to use for every object
