Hey! So, for Super Pac-Man, as it’s been remade from the ground-up due to the lack of proper documentations, I don’t really want it to be more accurate to the original, and thus, I won’t make any option to deactivate all the visual effects added in the process, sorry :c
You can still try to make either a patch or a replacement mod that aims for a more accurate gameplay loop and speed, if you are motivated.
For added features on Super Pac and Pac & Pal, I sadly don’t have any ideas besides mod support for more characters and more levels to be played on, as you can just replace or patch stuff for now.
A big thanks for your feedbacks tho, but yeah, if you want a more accurate Super Pac experience, I’m gonna quote you, "just play the original game then" :P as it’s not my current goal.
