Not a bad clone, just needs some polish.

Well first off, it's a fun game. It does need more fighters than just Sonic though...and I think that the coin generation is too slow...I haven't even unlocked Toad yet because I can't get past stage 3...hoping to change that though. But yea, I think the coin generating guys need some changing...the generate too slowly, and it'd be great if you could upgrade units. But yea, add in a few more actual attacking units and upgrades and it'd be really fun.

My principal concern is that Sonic is the only one real fighter, and it gets annoying that i cant get the coins right away when they appear, and i need to wait for them to land.

In general i liked it

It could use a little tweaking, but I liked it.

I like the game , but i think that it should be a speed up button because this games are slow and may some people don't like to wait (like me) but its okay and i hope you got luck whit this game
