Good little game, I don't know what guy commenting before me saying Reset not working, cause it works just fine just press R to reset the puzzle. Only missing thing I found was color Index meaning which color block stands for what, had to figure it out on my own with hit and trial.
Light Blue - Snowflakes
Orange - Nuclear Material
Green - Poison
Brown - Horses (to be saved)
Dark Blue - Snow Bomb (Only 1 bomb in this level)
White - Player Character
This game has good potential if creator makes more levels.
