Grimace's Birthday

Grimace's Birthday is a Game Boy Color-style platformer made for a McDonald's marketing campaign to celebrate its mascot Grimace's birthday. Grimace is tasked with finding his friends and collecting milkshakes for his birthday party.

The game has four levels with three different platforming styles. The first two levels have Grimace riding a skateboard, grinding on rails to get higher. The third level is a standard platformer, jumping over gaps and enemies. The final level has Grimace flying in a bubble that rises by tapping the jump button.

After the fourth level, the player chooses one of three screens to play a mini-game. It consists of a 2d shooting game where Grimace must blow out candles and pop passing balloons.
