My first impression of this game was "oh, it's like Stacklands", but after for a few minutes I'd it's not quite it. Although the gameplay is similar, the way you play it is more like an RPG (while Stacklands is more like a survival crafting).
I had a lot of fun playing until the end, but there were some bugged puzzles, some weird translation/localization that can make achievement hunting really challenging (had to seek guides in other languages with Google Translate to have a general idea of what to do).
Overall, I really liked the game and, for me, it was worth the money and time spent and I hope the developer keep making interesting games like this.
