The potential here is insane. The concept is super fun and unique. The execution, unfortunately, is super barebones, at least right now. You can make enough money to buy basically every upgrade in the skill tree and make the perfect machine in only the first 3 or so "zones". Once you've done that, if you want to "beat" the game you just have to sit and wait for like 10 minutes while your machine slowly digs its way through the whole level without any new content. There also doesn't seem to be any real win screen, just the extremely durable magma layer at the end. I think if there was just more outside of the length of the level then this game could really be something special. Like one of those games you'd see clones of on the app store. I hope the developer considers fleshing it out more!
