I question this very game's existence.
The First problem you will notice is the title screen; why does Sonic keep rolling in and out of the tunnel? And why did they even attempt 3D on an old console like the master system? The second (and the biggest kicker) is the speed. The speed will affect your gameplay throughout the game, who came up with the concept of slow sonic games being fun? and it really doesn't help that there is a TIMER. the only fast way of getting around fast is to spindash, but if you hit a wall, you'll bounce back and might hit a hazard! There are speed shoes you can get,(which make you run the speed sonic should run) but its limited time powerup, and there is an unnecessary background flashing if you pick up a powerup! the object of the game is to get three keys.
obtained by either destroying enemies, or just coming across them in the level. you get 1 minute on the timer, and each time you get a key, the timer goes up by 20 seconds. But when you get hit, you lose ALL your keys and they might fly off to ledges that take AGES to get to, and once you do, just to wind you up even more, the game makes them disappear and respawn them back to their original places. if that happens, you will run out of time. There are 16 levels in all, and 4 levels in every world. at the fourth level of every world, you will be sent down a slope to collect rings for the boss (note: this is the only time you can collect rings, and therefore, the only time you can have a non-time related death. When you beat a boss, you get a chaos emerald. only problem is, there is only four bosses, and if i remember correctly, one of them doesn't even give you a chaos emerald!
So this ends my first ever review. I think i ran through it all.
Final score: 2.0
