Thanks for playing and for the feedback! 

I was a little worried that I might be throwing too many mechanics towards the beginning, so reading that you enjoyed that was a big relief! (It was originally supposed to be spread across 10 levels instead of 6, but I ran out of time). 

I do apologize about the Windows crash bug! I've been trying to get it resolved the past few days but to no avail :(  I fear it might have to do with the structuring of how levels are saved and loaded which would require a lot of code to rewrite, but I'm not giving up yet!

Anyways, thanks for playing and I'll let you know if I can ever get that bug resolved!!
