What's actually the best strategy here? Get a good weapon and rush to the exit? Hasn't worked for me yet, but there doesn't seem to be a leveling system, so taking your time only makes the game harder and your character weaker afaik.
First thing: Enemies only get stronger if you fight them.
Don't go to the school when starting, if you really need/want to go there you can always head to the hotel.
Get the priestess outfit. Impossible to get rid of if you don't want to give blow/titjobs but it is the 2nd best starting outfit just way easier to get (princess is better but is RNG locked) all you need to do is walk to a room and lie on the altar to get it. With 12.3 and beta tester+ status
[edit] if you have a dick
[/edit] you should be able to get out of the dress fairly easy as well by helping a gladiator scratch their itch, makes it better then the princess as well .
You can get water and food from the guard(s) in the dungeon.
Stay in the dungeon as long as possible, with the priestess outfit you know when the altar is safe and that one gives only beneficial effects, only down side is that it can only increase your intelligence stat. The throne can boost all three stats but you risk getting the body expansion or dildo scenes. The stat boosts are worth it though.
Talk once with the Aeromancer to get the skill they offer then fight them, first time get that wand, other fights to permanently remove them.
You can risk wearing unknown clothing or drag the new piece of gear to the altar, equip it and if you get a curse you don't want (and you don't have that better curse option on, available to beta tester+ since 12.1) use the altar to get rid of it. The most interesting curse if you are looking for stat boosting is "sit on the throne" since that bypasses the usual cool down.
Know the difference between female and male/futanari sex dolls, the latter splatter when you defeat them so either go after them close to the lake or have cleaning rags with you (and then clean those in the lake).
Remember where traps are, it is better to evade then rely on the I've been here before (and triggered) it bonus.
The toilet is helpful when you are getting horny, you do want a minimum amount though to get that dexterity bonus though.
Seriously consider getting rid of all 'leaking' NPCs, except for the prison guard in the dungeon.
Once you get to 8 rings 'bribe' an NPC with the cheapest you have.
I normally don't advocate save scumming but in the case of chests (not crates, sacks, tree stumps or trunks) save, open, if it is not a recipe or a spell reload.
