Tetris with an extra twist of actually being on the board and therefore trying not to squish yourself. Though I did get squashed by my first piece placed before figuring out the concept.
It would be nice to either know where the player is on the 2d screen or have a shadow on the 3D screen to help judge if you are in danger.
Overall not a bad prototype/concept, but could do with something extra in relation to the 3d platforming side of things so its not just a regular game of Tetris. Maybe objects/coins you can grab for points that require you to deliberately build up to and reach certain heights.
But for only a 2 day submission, congrats on getting this far.
