Damn I hate you! I love this kind of games about combining things to create different elements. I have the curiosity to find them all but not the patience.
The game look very cool! The 3D models were simple but yet understandable.
I know is not as final as you wished and I would love to see a version which somehow could see the already discovered recipes, how fat I got my Piet and somehow a way to "spawn" already known recipes, because some complex ones are difficult to combine again and makes the game a bit tedious. Also, damnit Piet! You were not supposed to eat that ROCK! I had plans for it!
Loved it!
