Well...
You said if enough people asked for a charge shot, you'd add it. Well, I'm another one asking for it. Sorry, but for me it's like a staple of the Megaman series. Anyway, I had no problem with the game (that doesn't mean I didn't think it was hard), so I'll just leave you with a 5/5 and a 10/10 for capturing the feel of Megaman, hard labor creating sprites,coding, and so on.
