Was ok till the level with the moving wall. The one, where you have to run all the time. That one was bad. Starting all over again ... after 6 tries i was frustrated.
EDIT: i tried again. This time i was more lucky. But now there is the next level with a moving wall, this time from the bottom. Really, this kind of levels could need some save points in my mind.
Not bad, I din't like the music on the second level it was to grating on my ears.
good game, it would be great if you had the jump button at another key. There were some jumps that I failed because of this
This was fun! Looks great, everything works, level designs are really well made (the timed more stressful levels are spaced out), the way you introduced each new element and trick one by one makes it just right for me: challenging but not too easy (boring) nor too hard (frustrating) ... perfect! Maybe the only thing missing is a level select, still: 5/5 :)
The gameplay was quite enjoyable. Especially that you brought something new in every level. Good job!
