RunnerFall Demo

I have multiple problems with this game:
1: Controls aren't tight enough, half of the time it doesn't register a keypress (my keyboard functions perfectly)
2: It's in spanish, which puts off people that don't understand spanish
3: It's impossible to see if any kind of block will be moved when you touch it, that's not "challenging", it's deliberately screwing with your players.
4: It looks really bad.
