The 3D effect is really clever! Would be nice to know a bit more about the game play itself.
So, originally the gameplay was a mixture of Arkanoid and Bricks & Balls, but it didn't feel right when I prototyped it. I've been playing with the core mechanics for a while now and starting to settle on a casual, puzzler that requires the player to clear the screen to progress.
It's not clear in the video, but to progress to the next level, you need to get a least a 2-star rating, this causes the big gem to drop, once the big gem leaves the screen the score for that level is calculated.
Yesterday, however, I did some playtesting and we discussed the ending of a level - we both felt it needed tightening up as it's not obvious, it's also a little abrupt.
I'm thinking now about something like "ridiculous fishing" whereby collecting the little gems get used in some manner to end the level.
TLDR - The gameplay is still work in progress, the foundations are there I've just got to figure out a mechanic that ends the level.
