Game's pretty fun! Improvements that could be made are having the ghosts respawn on a timer that accelerates, instead of just respawning, because this essentially just is repositioning. Combined with the fact that shooting the ghosts on a Jim kills them all at the same time, the game encourages sitting on one Jim and healing him whenever available and spam firing at the ghosts. The only other major changes I would add is positioning the player health bar about the player, so its easier to see your health. Frequently I would die, because I didn't check my health, and when I did, I would get hit. Finally, sound effects go a long way. In the end, it's still a great game for 48 hours.
