This isn't that great to be honest....but it's a good start... From the very first battle, it wen't all downhill.
Here's my thoughts on the game, and I will put some possible changes and fixes for you.
* The enemies are overpowered with their basic attack damage. Reduce it!
* Limit Break skill does way too little damage. Raise it!
* The Healing costs too much MP, again, Reduce it!
* Add some items, potions of healing or something else useful.
* Make each episode longer, or simply make more episodes!
* Since when does Tails have a GUN?? - Keep the game to it's original attacks like the Genesis did.
* There's no chance of surviving Metal Sonic assault, but maybe that's the idea. I think it might be, so disregard the last one if that's the case.
