Thanks for the kind feedback :D
And actually, concerning the lag.
It may have lagged worse for you because you were completing the levels so fast :)
As the levels are un-loaded they remain off to the side and slowly deconstruct so as to not affect performance too much.
If you complete the levels quickly they can't deconstruct fast enough and things start to lag
You're just too good :)
Thanks again and good luck with the jam!
