Well, I haven't programmed the boss yet, I'm still trying to decide if I'll use my original idea for the boss. Since Blocky Man is based on Super Mario, and boss battles in Super Mario don't tend to be that epic, this will probably be the same. Although, I was considering putting the Baron in a giant mech.

So it seems there are some interesting things being done with XNA,

">such as having a Xbox 360 read input from a Wiimote.

">Ofcourse, emulators are being written with XNA, although performance seems to be quite an issue. I'm just hoping to see some hobbyist games being made with XNA in the near future. Ofcourse, my next project will be with XNA, but that won't be for at least another month, until I finish Blocky Man.
