It's a fun game with good visuals (for its time) and creative and engaging puzzles. Some puzzles can get tedious as they require you to pixel hunt tho. I'd recommend the PC version over the mobile (Even though the mobile port is good).

It's Puyo Puyo but Sonic themed. It's surprisingly a hard game. If you're a Puyo Puyo master, this might be a fun challenge for you but for a beginner like me, this is hell. I could only make it to Stage 2.

Childhood - "This is a fun game!"
Adolescence - "This game is mid compared to Half-Life"
Adulthood - Realizing that this game is its own thing and appreciating the simplicity and the beauty of it
