Strawberry Xmas Walkthrough Cool Math Games

Strawberry Xmas is a small platformer game created for pico 8 platform. The main character of the game should collect as much as possible strawberries. At each level there is an exit to the next level, but sometimes the exit is closed and in order for it to open it is necessary to collect all the keys that are on the level. It is inconvenient that if you went out of the level, but did not pick strawberries on the previous one, then you can’t go back.
