I have played it, and finished it, and I liked it, really.
First of all I got welcomed by the music and I liked it, it fits the game very well, and also the 3D models are nice and well made, the idea is interesting, it definitely lacks more mechanics, power-ups, maybe, something to clear the table, or make it that it is 50/50 whether it clears or adds mode debris, make it that it can be endless, with these simple controls you can port it to mobile phones, your choices.
I would really love to see this game evolving, as it's holding a lot of potential, but anyway, great game!
Also, a tip I got from other guys, for future jams, make the game available to play it in browser, as many people just don't bother downloading games.
