Sonic is cool
sonic is pretty cool, and this was a decent game, i did however think the viewscreen of it all was kinda small, so as an idea or tip here try making the palate or view screen much larger and bigger, and the hedgehog could of used more items of the hair type the blue spiky type of stuff so i guess you could call it hair but he needs more props of that, the backround was notbad, maybe some more added backrounds like on a selector of backrounds, and nice option on the music thats another area where you could add a cycle of music selections, After seeing and messing with this one i thought it was great, its a decent flash there is room for improvment, and you should think about adding some new stuff as mentioned below and even in the above review lines, it will be great for all, anywayskeep up the work i like the effort you put in sofar, and look forward to seeing more. Anyways keep up the decent work here.
~~THINGS TO IMPROVE ON~~
So this is were I suggest some ideas and tips to better improve stuff, Your game is actually pretty good doesnt need much but could use a few things. the music thats another area where you could add a cycle of music selections, the hair type the blue spiky type of stuff so i guess you could call it hair but he needs more props of that, So as a tip or two, you could work on your backrounds more, what you have is ok but having the backrounds more enhanced with some sorta design would be one way, or some image in the backround that is somehow related to your game. so these idea and tips could make it a better game give them a try cant hurt at all, just a little more effort thats all.
