I think it's a very cute game, but in my opinion it needs some improvement in the UI area... I didn't know how many rocks I had, I think they are missing from the inventory. I also found a bit annoying having to jump so much between the inventory, recipes and "maker devices" screens, I wished there was a better way to navigate this information, maybe having a fixed bar showing the inventory would help? Although I know that could take up too much space of the screen. I thought the graphics were very cute, just a bit confusing for some items (like the symbol for plastic or clay, they don't seem very descriptive). I rated the music so low because it becomes repetitive very quickly, so, I get the spirit of it, but I think some variation would help it a lot. Good work in any case! Thanks!
