I spotted this game through your video that you posted discussing its development. This game seems really polished and well done! Reminds me a lot of Roller Coaster Tycoon... which I never played, so I cant actually speak to how valid this comparison is haha. The art style/visuals are really solid, and the sound effects are pretty great for creating and riding the tracks. I think the controls are decent given the amount of functions you're able to do, and what you're able to do in this game is really technically impressive! I struggled to get past the tutorial, however, as I couldn't build enough momentum to reach the highest orb - considering most of the other comments haven't mentioned it, I'm going to give the benefit of the doubt and say that I'm stupid. Really polished and nicely made game, impressive work!
