Really cool concept! It was pretty simple to grasp imo, and I think a puzzle game like this has a lot of potential! At first I was a bit confused as to why the pipes won't rotate, but I soon inferred that it was because the pipes didn't have space to rotate, which was a really cool learning moment ngl, I love non-tutorial tutorials, just wish it was a bit clearer with maybe a visual cue of some sorts. Also despite the visuals being quite barebones, it still looked felt quite polished because of the transitions and menu animations, so props to you on that! Only other downside I would say is that there was no audio. Sound effects in a game like this would elevate it greatly! Still great game doe 🙏🙏🙏
