Hey fun game. Not too challenging which is nice - I was ALMOST getting frustrated on a couple levels. Easy and quick enough to start and complete while working (EH? EH?) A couple tips for your next game:
• having to left click for next level while playing with the arrows was intrusive
• spice up the different levels with different colored purbalds
• maybe make restarting the level a hair faster
Not sure what else to say, I played the whole thing so it was engaging enough. No ending screen with cute sleeping purbalds though, that's a missed op right there.
