Very interesting game. The overall environment feels open and focused, and the sphere mechanic is a joy to play. I found the ricochet mechanic hard to get used to at first, but once I got used to it, it added an enjoyable strategic dimension. I think consideration could be given to adding a how-to guide or some visual elements early on in the game to make it clearer. All in all, it was a short but fun experience, and I'd look forward to more sphere powers or levels if they came along!
