Wow, you did this all in 48 hours! WOW! Amazing and good job!
I enjoyed how the control was reverse, simple but on theme and made my brain go "huh?!"
Easy to start and play right away (thank you), levels got more challenging but still were well explained (thank you) and fun to solve.
This is the best game I've played so far while rating!
The only feedback would be to update splash screen, the simple penguin doesn't give the fun of your game justice. Maybe add more of a map view?
