Amazing concept. The only negative aspect to this game is the fact that the jumping is pretty hard to control. Try making it so that you can control trajectory mid-air with WASD and can control the speed and such with the mouse (as before).
Reviews for "TimeLine Runner"
It's pretty good, controls are good, graphics are simple but effective, and music is good. But a big problem that gets very annoying after a while is how the music stops when you jump. This sounds like a small problem, but it gets very annoying very quickly.
Beautiful game, liked the concept. Music here is great, i'd like to know the composer. Controls could be better though. I played with mouse and sometimes gestures would suddenly interrupt leading me to inevidable death. Also a timer showing sliding time left would help.
I like the checkpoints. There are checkpoints, by the way. What I would really like is a way to save progress so I can close the browser window and then later still restart from 1434. I also liked the way you made it 1:1 between the mouse movement for a jump and the distance traveled by your head. Some of those propeller obstacles, though. Hard to get anything going sometimes. It was also frustrating to want to do two jumps in quick succession, only to have the second one come out as a slide instead.
All that said, I'm still playing it, and I came back to it after sleeping. Good stuff.
I don't know why you guys think there are checkpoints, There are a ton. I prefer using wasd, not mouse. This is a really addictive and challenging game. Awesome!
