First off, this game runs perfectly through Wine on my Linux machine, so you should be able to get it working as well if that happens to be your OS of choice.
This game is absolutely adorable. I enjoy peaceful games quite a bit and this one is really sweet. Of course, if casual carefree games don't really interest you this game will have very little to do. I recommend this game to anyone looking for a cutesy little game to spend some time on and relax. I am having a good deal of fun.
One reasonable feature I'd like to see if another patch is planned is some way to screenshot without having the placement grid visible. As far as I can tell right now, photo mode only will show the whole build and being on a specific layer always shows a grid where things can be placed. It would be nice if photo mode maintained your current layer view and hid the grid so you could get pretty screenshots of indoor areas, for example.
A less reasonable feature that part of me wishes was available was some way for the shroomies to harvest or otherwise obtain mushrooms to use them to build. I duplicated a save file where I built a nice wooden house and modified it to turn the house into mushroom blocks (replacing the wood) and the result makes me wish there was some way to replicate it in a gameplay fashion. Only having wooden buildings available is a tad limiting and being able to use mushrooms in this way would help spice up a lot of builds. That said, I can understand this feature not existing because it would require some relatively large addition (like a new mechanic or resource to obtain).
