In the first 10m of my windows game, i pass through 3 blue/scared ghosts already (instead of eating them, often with boost ON... and most of the times when blue ghosts were coming toward me... for reproducibility; then later, phased one red ghost in lethal form frontally too, so it is not only their "scared forms"! ʕᵔᴥᵔ࣢ʔ)

It seems the collision behavior need a bit of tweaking still (in the  1.0)

(it didn't occur when playing Pac-Man & Pac-Man+ Rewritten... even if natively these games has some exploit i have read/seen with a "one pixel precision phase-through"; from memory, it has been corrected in Ms-Pacman and are impossible because the hit box has been enlarged or something similar.)

But overall, a great game for PC! thankx a lot! (feel & look even better than "Tengen Ms pac-man ROMs" on all console for 1P play! SNES version has 2D/3D enhanced graphics and 2P but still! Classic look here is impeccable! ʕ♡ᴥ♡ʔ)
