Space Plumber is out now on Apple Store. I still didn't release on PlayStore because I found a crash problem in some device models and I'm trying to find out the reason.
If you're playing using iPhone you can use 5 simultaneous touches in some levels (which is the device limit). On iPad you can use up to 10 simultaneous touches.
A little about this game: it's a free casual puzzle mostly for kids, using multi-touch features. Although it requires some logic, most of the puzzles can be solved by using only a trial and error approach.
There's also a video on Apple Store. As soon as I upload on YouTube I post here.
Special thanks to Markus and GarBenjamin who taught me so much about programming games! I couldn't have released this game without the help of this community.
Next: finishing a tutorial to release on the next version.
