Thank you so much for the thoughtful feedback!
You actually pointed out one of the biggest challenges I faced during development. The characters move on a grid, but the world itself is not grid-based. Because of that, keeping everything perfectly aligned became surprisingly difficult, and to avoid introducing frustrating situations, I ended up making some of the early levels a bit more forgiving than originally planned.
I completely agree that adding more obstacles and creating a smoother difficulty curve would make the progression more engaging, and that's something I want to improve moving forward.
I'm also very happy to hear your thoughts about a mobile release. I was fortunate enough to get a developer account for the Play Store, so that's currently the main platform I'm planning to launch on. My next steps are to improve and polish the game based on all the feedback I've received, and then start preparing both the publication process and an expansion of the game's content.
Thank you again for playing and for the encouragement. Comments like this help a lot!
