Turing Compete by Kaisean Games 2017-05-03T09:13:36Z
Quite hard to get this at first, but very enjoyable when you understand it. Maybe the game needs to be more intuitive, and help you in the proccess of making a machine that works. I kinda like that there's no compete mode, and the just let you be creative with the machine.
Not my kind of game, I must say, but I found it enjoyable and I had fun trying to make something that works (and I even made one, hah!). As far as I know, this kind of games have a lot of potential and there are some games like this on Steam, so you could improve and expand this, I'm sure a lot of people can find this interesting.
