I've been working on a completely free and add free android game as a passion project for the past few weeks or so and I've finally managed to release to the Play store and the Amazon App store a few days ago.
The game in question is called Super Stacker and you're objective is to create a tower by dropping blocks on a spinning base and alleging them perfectly. Super Stacker is a non-profit game and as such is completely free of charge, contains no ads and no micrtoransactions.
If it looks like something you'd like to play, give it a shot and let me know of your thoughts. I'm more than happy to receive any feedback you may have for me.
