Another epic adventure imo, regardless of AVGN's review   This game got me through a summer stuck at home living out in the country where there wasn't much else to do. So much to see and do in this game.
One of the hacks also gives you all of Dracula's relics by accident when you buy a white crystal in the opening town but I didn't take the time to research which one it is. Probably the 'Buy all weapons' one :p

Just saw Dead_Media_Archives playing this on Tiktok Live. I'd never heard of it before and wanted to give it a go. Still impossible even with all these hacks!

Heard about this one on Tiktok, too. Never heard of it but a simple take on it after a few attempts is it's friggin' HARD. Controlling the ship is different, to say the least. Anyway, here's a few to take the edge off :p
