Do you have any problems downloading other rpgmaker games? If so it might be a problem with your device, otherwise I'll look into it.
Most rpgmaker games run smoothly and without major problems, i have spent a lot of time in Lust Doll Plus, Elf Jail, Yorna: Monster Girl's Secrets and some other games. I only had problems installing some of these when my storage was almost full, but i cleared a lot of stuff and there should be plenty of space.
