I noticed that in the remake road map you missed some enemys like the wasp or dragon fly

“Wasp” was just an H-event to enjoy in the original version, there was no story or scenario about it, so naturally it wasn't shown in the remake, and this part will be designed by our own original after 1.0.
“Dragonfly” I can only regret, because in the original it was also only used to test CG animations (and there were only 5 CGs, so it was almost hard to use), so I think there's a big chance it won't be added.
