EDIT: If you have Chrome problems - won't detect "Click to start" then please try switching to different TAB and back, this fixes it, it seems. Bug in Unity or Chrome.
EDIT: it seems some versions of Chrome have problems with click detection in Unity - never come across this before, I think it may be the multiple cameras.
Please try in another browser if "Click to start" fails in Chrome - thank you for your patience!

Click the blocks to collect them in groups. You can only see the top layer of blocks to start with, more is revealed _ahem_ BENEATH as you click away...
I used the excellent Unity to create this little game. I've only submitted a web version and source, ran out of time to test on multiple platforms, seems to work Windows 7 or 8, IE or Chrome. Please let me know if you find different !
As well as Unity I used BXFR, Audacity and a little bit of NGUI.
The piano playing is me also, recorded with phone and doctored with Audacity.
If you are building from Source you will need Unity 4 with NGUI in your project - please let me know if you run into any problems.
