I don't know why, but the speed run and double jump don't work for me
I think it's because it was made in old version of Construct. I'll show you how to make it work for part5.cap, but you'll have to repeat it for all later parts.
I suppose it doesn't work because there is an % sign in Controls Event Sheet. You'll have to erase them all.
First is - Player %1 "Action" is down. To erase it you'll have to double click it and then click Finish, then repeat with 3 others. In part.6 there are 18 % , because there is swimming and ladders.
Hope it helps, maybe there is a better way, but this is only one I know and it works for me
