Aside from this not being a game, and only having one question. Make sure you use better handwriting or computer generated text, because I can hardly read anything. Second, the rainbow colored text is hard don the eyes and nearly impossible to read.
Endless, though it would be hard to stack nothing but lines on end, you would get 4,000 points. You can get about 250 every ten blocks by stacking them all vertical. So 600 is hard, but not impossible.
Weel, I like the devoloper, but don't think a score should be based on that... I give it a 4/5. The only dray back is the graphics. They are simplistic. I'm sure that was the direction you were going for, as with your other games, just doesn't seem to suit my tastes. I do thoroughly enjoy it. API please. :)
On lvl 20, make sure you fall straight down. you shouldnt have aproblem then. and if you do, rewinding normally fixes it. 4.5/5 great game, but fix some glitches.
There is a bug that when you place a teleport, and then suicide, you start at the teleport, and i got a time of around 28 seconds, and didnt get any new levels, i'm guessing that is all there is on this version.
