pretty fun game

my time 8min and I forgot the seconds

are the birds in a cave without walls? or outside with a roof im confused 

but still fun

They supposed to be outside, but i enclosed the play area, so you can't just fly off and screw yourself over, since you have to restart the game then.

I could done it with some code, and teleportation maybe, but this seemed the fastest solution.

Nice time! Maybe try to improve your time, if you have some free time laying around! ;)
