The core concept of Number Stomper is simple. Each time you roll onto a tile, the number on the tile will get reduced by one. The initial handful of levels gently increases it’s difficulty, and will also introduce special tiles that start to complicate moving around the map.
The Demo has 25 levels, while the full version of the game is only 4.99 and adds another 75. There are only a handful of reviews, but they’re all positive, so if you enjoy the demo, you should probably pick up the full game, it seems like it’s a solo/self-published dev, but the overall game feel is polished enough.
