Wow, this is so much more than I was expecting. It's really excellent. Factorio is one of the games I've played most in my life, and this certainly stands up against it. I will be playing this fully once it releases. Tutorial was great, the possibilities feel dizzying. Interaction system feels intuitive, only took a short bit of time to use it fluidly. Very fun seeing unexpected things happen, and chaos unfold. When the roller started bulldozing me and a tree through everything I build it was hilarious. Gotta be better about welding.
Deserves a better name and player sprite, that's my only comments. The name is really wacky and doesn't capture what the game is about at all, in my opinion. Perhaps its memorable, but conjures images of a silly cowboy game or something. Consider the most important vector of a game becoming popular, people telling their friends about it. "Dude, have you tried Roody Toody? It's awesome!". It doesn't sound cool, it requires a lot of "I know it sounds dumb but trust me" type stuff. Or think about when you try and explain what you're working on to your dad. "What is the game you're making, son?" Do you really want to say "Roody Toody"? This stuff is important. Factorio is a perfect name. It sounds mathematical, complicated, and kind of sophisticated. It instantly primes someone for what to expect. Minecraft, Infinifactory, SHENZEN I/O. Those are good names. Even Satisfactory, a kind of stupid name, is better. And your game is already better than that one. Anyway, I've said my piece there.
The concept of the player sprite is great, I like that he is 1 block in size exactly, that's perfect. And the mask coming down when going into welding mode is an excellent touch. But at first he looks like a tard with some orange clown hair. He doesn't have an iconic look, when I really think he should.
Great work. Carry on
