That is interesting to play! I played a lot of pacman remixes games over the years, and this one is surprisingly good!
You respected the old school graphics and gameplay, but added undertale/RPG mecanics to it and it is very cool to play! Well done. I had fun. (its kinda hard! i loved the random multiple attacks of the 3 ghosts!)
free ideas:
Kniting "eating the dot" into the fighting-gameplay to make reappear the pac-gum to hit the enemy (like in the DX series when finishing a loop-run to go to the next), and chasing some/multiple moving fruits to gain a life back (each fruit could give 1/2 or 1/3 of a life) could be the hard mode; or toward a full-fledged game with those mecaniscs!
