An easy way to fix the impossible jumps would be beneath your "If Random Number is Equal To 3" behaviour add the following behaviours:

"Behaviour Off: Timer" -> "Wait X Seconds" -> "Behaviour On: Timer (Skip Events On)"

Very nice. I had to go in and look at some of the things you were doing. Couple changes I found:

• Rather than using "Combine Text" with "-" and your number, you can use "Subtract Value" with "0" and your number. This will fix some bugs where you were taking a negative number and put a second minus sign in front.

• Also for your collisions, try imagining where the base of your object would be and use that (e.g. http://imgur.com/a/0sYll ) Beyond that, it may require a little bit of fine tuning to get the edges to line up perfectly. You want the player to be able to slide along an edge and not get stuck on tiny little corners from your collision mesh. Turning on Object Boundaries when playing your game in debug mode is useful here.

• We're not interested in collisions for "Wgen", "Gen gen" and "Dirt tile". Changing these from "Wall Objects" to "Scenery Objects" will help with performance especially during the initial load.

What about something like this? Everything is being done inside the arrow keys. I've only commented my logic for "UP". Also, the link is going to expire in 7 days.

Nice game. Instead of using the red bar as a button, you could have a large invisible button fill the screen so that players can tap anywhere. Just make sure that power-ups spawn in front.
