The concept of this game is great, but there seems to be a bug for some players which makes them lose automatically on Level 4... which is a real shame. But from what I've seen it looks like a very cute little puzzler and I'd be interested to play it for a bit longer.
However, aside from the bug I also feel as though the graphics could have been better integrated with each other, and the big "ad screen" IS very annoying. It seems to be what causes the game to slow right down at points (i.e. the glowing orbs will suddenly start to slow down, and then speed up again). Finally for some reason the orbs just feel slightly sluggish on screen, even when my computer's running at full throttle. Do they speed up in later levels or something? :)
Anyway, it's an alright game and the concept is good... just a little tightening here and there could help turn the game from good to great. I wish you good luck Daniel. :)
