My Name is Mayo, Squareboy vs Bullies, and Energy Cycle.
Six super easy, multi-platform stackable platinums.
Goosebumps:The Game was also super easy.
MNiM, Energy Cycle, and Goosebumps were bought solely for easy, quick plats.
Day of the Tentacle and Odin Sphere: Leifthrasir were the easiest plats from games I bought because I actually wanted to play them.
