Try Kiyoshi's links with http instead of https to make them work.
I've only tried "reflexions". Nice concept.
But on firefox, it hicups a lot (far more than C2's games do) and I had no sound.
Also their loading screen on start of the application is strange as it will rush to 70% and hold there for a while as datas get downloaded.
Maybe it was sound I was downloading, that makes it just more painful that the game was silent.
The concept is interesting, but the performances don't keep me far more than a few levels.
