Hello. If you mean the jump where you have to jump across the gap, you can use shift button to increase your speed. Maybe this will help. Let me know if it does and you reach the end :)
Thanks for pointing that issue out. As this game was my first game, it is not polished and there may be some bugs. In level 2 there was a moving platform with spikes. Now that I have updated the game, it is visible.
Let me know if you have any questions or feedback! Have fun!
