We were finally able to finish a whole stage with all enemies, objects and bosses. (This doesn't mean that we only have this stage done, is just that other areas are not 100% feature complete like this one)
This run was done on B Class with no Final Four active. On A Class, there are several more enemy spawns. On S Class, all enemies and bosses get more AI and/or new attacks.
I just did a complete revamp on the physics and player animations to play more like the snes games, so I figured I would re-upload this stage video to show the difference and why not make it S Clas...
