Not exactly, his overheating just changes the movement speed and frame delay to make animations faster. All the other mechanics remain the same.
However, his speed can affect the way the range parameter works, since he will stay closer most of the time at higher speeds and will use certain moves more often than others.
for the official release, this is the content planned so far:
- SOR1 content: Blaze and Adam, Hockey Mask Guy, Bad Ending
- BKM content: all levels as alternative routes in the SOR1 one
- Beta Zan (still needs more sprites, but is on the way).
- SMS/GG content: some enemies and levels
- Some custom characters like Super Shiva and Ninjo (sent by Adrimus)
- Add all remaining cpu partners, and test 3 cpus at the same time
- Improvements in all playable enemies
And after the official release, I'm still considering adding the SOR Kamurocho route and starting tests with SOR4 content.
