the_clown@ I simply googled for them, then I've adapted them for Acknex one by one.
Superku@ I would love to see that movement in action, if you could show a video or so, that might look interesting I think that I'll keep player's movement as simple as possible (running/walking/jumping), it's just an fps at the end. I already have few ideas for enemies (this is the main goal for me, to make different behaviors for them).
rayp@ dude, CED rocks! I use it quiet a lot, but most of the complex sprites were created by hand.. Cause I've found some troubles in CED (with adjusting the height, width of the sprites).
