Sonic Blast is, by far, the best sonic game on the game gear.
The Good:
-Loads of fun levels to play as either sonic or knuckles
-You can now climb trees(a power I've looked for in sonic for ages!)
-Graphics are quite good, especially for the time it was made
-Boss levels are very fun to play
-Highly addictive, side-scroling gameplay
The Bad:
-The game gear couldn't hold as much content as other consoles of it's time
-The first 10 levels or so are pretty easy to breeze through.
Overall, Sonic Blast is, by far, the best sonic game on the game gear.It combines some solid platforming with two great playable characters and highly fun boss levels.
Overall, 8.5/10
