The basic idea of a size based platformer is interessting, but it depends on what levels you build with them
So the two levels we got were just not enough, atleast for me, to see how this could be expanded or what the direction this game wants to go in
On the other hand, this is a game jam, so it's unreasonable for me to expect any more levels
And I liked that in the last part of the second level you can get around the last obstacle being either big or small
Overall, in it's current form, the game is to basic and unfinished, but the premise is good enough to built a full game atop of it
