Hello everyone

So I've been wondering for a while about what a game is called, but I can't even recall a letter from the title.I used to play this game around maybe 2010 and it can run on an old PC system (Windows 95 probably or another similiar old system). The game was 3D. You could view your character from a bird's eye view.The characters you play as are genderless and there are two. I believe you played as two characters on every level and the characrters looked liked m&ms except without a logo on its front and smaller legs and arms. There was no soundtrack. The goal in the game was to get past obstacles (pushing boxes to activate a certain thing,solving puzzles etc.) and once past all of the obstacles you fall into a rainbow hole, in order to procceed to the next level. The levels looked something similiar to the game Hopmon (by Saito Games) except everything is a bright yellow color and had more different envoirments (on some of the levels there was grass and I think blue voids or water). As for collectables, there were stars on every level you can collect and they made a sound everytime you collect them. They also made a sound when you finish the level, so they went:"Wheee!".For now, this is descreptive as I can be for the game.
