In the style of the old Wonder Boy in Monster Land this is great! The art, music, and level design is top notch! The controls are also very tight, for a Wonder Boy clone.. BUT. it can be incredibly punishing at times.. lots of rooms have needlessly many enemies and they have a penchant of spawning flying enemies when you have to do jumping thats its not even fair. You cant even avoid the enemies since they just gang up and follow you through the whole room! The fast travel and checkpoint system is also needlessly spaced out. You end up running through several areas anyway to get where you want, wasting lots and lots of time and money (from dying again and again just to travel to a new place) So, again. i LOVE this game, but i also HATE it!
Its kinda like Terraria, just that the Dwarfes do their own thing. But you can give them equipment and weapons, you can upgrade their skills etc, which is a must if you want to survive whats below. At night you get attacked, which isnt a big deal once you build some fortifications. While the UI may look simple and made for a touch screen, i only used a mouse and keyboard and didnt notice anything out of the ordenary. No DLCs required to enjoy it either, they are there for people like me who just cant get enough ;)
