That feeling when you need to step on heads to complete the game. The game is cool in style. The drawing style is simple but cool. It's cool that you worked with particles, it's really on topic. I didn't like that there is no limit on the number of objects on the stage. You can break the game with such a meta, which is what I did by spawning a lot of marshpilow and pushing myself out of the map.
Also, if you throw a marshpilow when you get close to a wall, it will stay behind it. I assume that this is because of where the throw point is. It stands in the wall and the collision pushes it out. This can be fixed with an additional check or you can make the level border wider than one tile as an addition to the first point.
