Simple and short, perfect for a 5 minute game. I'd love to see and extended version though, I'll be waiting till the day it's either known to never come out or the day it's released.
Personally I am a massive fan of the games you make, a very creative twist on what puzzle games are. Only had to use 2 hints throughout my playthrough. Can't wait for the next game you make.
Thank you. Who knows... :)
