At first, it was kinda hard to understand whats happening, but after that i got it ( I had to read the game description ).
I like how it gets harder and harder, so you have to make an a strategy to not lose. But it was kinda confusing because you did not know how many black sheeps could enter before you lose, thing that kinda confused me.
Also i liked the upgrading system, but i would like it even more if it was more visual instead of text.
Finally i loved how the game was like a cube! Is like it was a game made for a Gameboy or something like that, i liked that a lot, it was a small thing, but i liked it
