How swell, my first time to peak in this forum and I find a nice game clone. 
The background looks really great too, perhaps it would be better fitting to the foreground with more sand-yellow-ish color tones though. And I love the player brick texture! The little ivy detail is perfect on the dark stone!
Three things:
- I think the delay between falling and restarting is too long.
- There should be a fall sound added (I might come up with one later maybe)
- Making the game open source and putting it on github.com/ for example will ensure that it won’t disappear thanks to arcor
PS: I recorded a video of me playing the first few levels: youtube.com/watch?v=RH1vhttDTXc
