it lags like hell for me. When I enter a level, it starts being unplayable.
I use s9+
I played many other sort of games and it worked fine.
Also, the pistons are bad, if you put finger at the head, it just instantly moves out.
Hopefully you soon add a star system and maybe settings with graphic (in case).
Also, I got the idea to add editor, and so, launch small updates every week just for bugs and new features without resetting level.
I know that a developer does hard work, and being paid will make him be able to advance, so, maybe for March 30, maybe publish it on Google play and add an ad which make sure you will put the name on it, so that they wont steal you. I seen many ads made from small reactions from youtubers.
