All fully leveled up at day 108 (but then I probably spent at least 15 balls to catch a stupid Caterpie... X3 ) and I like what I'm seeing so far. No full score, though, because of the unfinished state, and I prefer to be conservative.
There are a few good ideas among the previous comments, so I'm not going to reherse those, but I've got a few more suggestions:
1. Minimap (Fly) - It takes a lot of clicking to go back and forth between the ranches and the hotel. I assume you'll add more hotels with any eventual new towns, but there'll still probably be a fair bunch of walking around.
2. Rolling clock - Actually, you could probably skip the hotels altogether and just flip around the clock to morning when the final energy is spent. You never really sleep in the original Pokémon games, anyway. Given, I can see its use as a Pokécenter substitute before any battle mechanics are in place...
3. Multiple sex scenes - This may very well be the plan, but multiple sex scenes for each Pussymon would be nice. For one, I'm personally sligthly turned off by anal sex, but it doesn't bother me if there are sufficiently many alternatives. An idea would be to unlock petting and oral sex already at lower levels and move on to more intimate action as you level up.
4. Party - One thing I like about Pokémon is how attached I get to my main team, with individual names and all. If I had to trade away one of them, I would catch the same Pokémon again and trade it away instead. If I could have the ability to catch several of the same Pussymon and give them unique names in this game like in Pokémon, I'd be really happy, because, well, I like growing attached. Right now, the game forces me to feel conflicted about it by making me trade away high-leveled Pussymon. This also meshes well with the evolution idea someone mentioned earler.
5. Hotkeys - Flash has a nice function in that you can highlight listening areas of a screen (buttons, essentially) by clicking tab, jump between them using the arrow buttons and select them using space. This greatly helped me speed through the leveling part of the game, and also helped me with the Pussymon hunt, since it's hard to make good, swift sweeps on a touchpad. Assigning hotkeys to the Bag, Care and Fuck buttons would go a long way to mitigate the tedious parts of this game.
