For a game jam game, it's pretty neat. Obviously short, and a bit unbalanced. By level 20 of radius I was basically covering the whole field with only two dinamites. It has some minor issues, like you can't skip animations, you have to just sit and watch all the ores slowly adding to your score, a forced scroll to the upgrades panel, and you're forced to place all the dinamites, even if you already covered the whole field (like I said, I only needed two dinamites by the end, but I was still forced to place 9 and watch the explode animation every time). It's very very grindy at the end, since the upgrades don't scale properly, for instance the "Rocks Amount" price scale too much compared to just giving you 5 more rocks.

In any case, this feels like a good base to make into several levels, with different minerals, more elements, achievements, different challenges and it sure looks to be at least a very fun mobile game, or even a PC one.
