Oh what if you add terrain effects that have a positive effect, add sexy events to those and boom! Double reward! Also cum pool would be funny to have XD.
Here are the 4 characters that probably won't make an appearance:
The acrobat was reworked into Miriel, so I guess he is in the game in spirit. The game was intended to have a single protagonist, but sorceress and wolf boy ended up with a very even split, so the fearless warrior was the only one that got left out. Unicorn girl was the second least voted character. "Dragon Hoard" was an unpopular option in the Bastion room poll, so I guess that female beasts are just not trendy. I do rather enjoy those types of characters myself, so I like to include them as a wildcard option.
There are another 3 characters that appeared in the poll, but are not in the game yet that may get added later. I think that there should be enough room for 1 more innkeeper, 2 clients and the sprout queen.
