Thanks for an honest review.Yes we heard about our controls being buggy and we did not get the game tested from a non developer person...for us the game was playable in all the levels if we timed our jump perfectly.We will improve on that next time.
Also if you still wanna complete the level...the player does not jump on ramp instead go to the flat area near the 2nd box in level 2 and jump from there
And
There should be a small time difference between running and jumping they wont work if they are pressed togehther in short time.
