Image 1 - The player, caveman, is idling in place yet dealing punch damage. This bug is quite reproducible, and apparent when playing any mode with any character. The game seems to snag at times causing the player to "skate" around the arena, while still being able to deal damage. Also, keys like (L) for the specials don't seem as responsive when this bug is occurring.
Image 2 - With "god" mode enable the caveman takes on a "Survival Mode" session. The enemies were all removed upon death with a couple of weird animation transitions. No undead bugs from the enemies but as you can see, the player was disabled with a jump punch from one of the aliens and lost all collision and then idled in place. Turning off "god" mode was possible but nothing happened. However, the boss continues to lose 5 health every five seconds.
Conclusion: Boss finally dies but many minions still remain. Overall, this build is an improvement from previous iterations with fewer game ending bugs. The skating/idling punch/kick/ bug though not a game ending bug is prevalent. The only game ending bug was the player not dying. Sprite choreography and polish is sorely needed. Ninja guard up walk animation still needs tweaking.
