I think there's a lot of potential here. I love the appearance and the concept. I enjoy puzzle games but I like them to be a bit more relaxing so I'd also rather not have a timer mechanic, or at least a timer mechanic with stars.
I don't even mind needed full stars to have to progress, for example, but I just want to be able to finish the level even if it's gone badly.
I think the controls and getting the pieces the right way is difficult, which is another reason I wanted to finish - just to practice it! If this was polished up, I'd definitely consider buying on steam one day.
