Awesome! It seems you take it serious, I like it. Don´t forget to mention the people who helped you. Because it´s not only made by Bonaf yet Do you know the title screen for R.C. Grand Prix? This should be a good way to mention your helpers.
Don't worry, It was my intention to mention the guys who helped me ! I was thinking of making a credit page, but rolling credits on the title screen like in RC Grand Prix is a good idea too (even better, I can do both ).
Since I can't add everyone, I need to make choices, so I've decided that in the first time I'll focus first on Sega exclusive characters with smaller sprites. So no Mickey, Donald, Asterix or guys from Double Dragon.
Bigger characters like the heroes from Altered Beast or Golden Axe need multiple sprites and much more work to add. Besides, I'm not sure how they'll work with smaller characters gameplay wise. So I've not yet decided on these.
I've not yet decided too to bring in the different attires (the Shinobi world Alex would be great though !). I'd also like to add a couple of iconic enemies but I'm not sure who...
Other characters I'm pretty sure I'll add : - Sonic - JJ from Zillion - Joe Musashi - a couple of surprises, I won't say more at this point
