Bought this on steam, and absolutely loved it!
Has it got problems? Yes, it does. The AI gets caught on walls and obstacles, I've crashed a few times, and it's not very challenging. On the other hand, I love it to bits! The stealth is excellent, it's all super hot, and you find that just when you think you're safe, difficulty comes around the corner. I might not be saying this if I'd bought it full price, but I definitely feel it's worth the money I spent!
The only things I would suggest (apart from more maps and content, which I assume are being worked on now):
-achievements: This game can be extra fun when you set yourself extra goals, like, CV everyone in the level, or things like that. Special goals to achieve would help make the levels even more interesting and fun to explore. Alternatively...
-collectables: Again, something to encourage exploration of the level, finding hidden secrets and ideas.
-alternative dialogue mode: This may just be me, but I feel that being able to customise the dialogue of NPC's and the Agent during vore scenes, to help fit personal tastes, would be very fun! For instance, making the vore fatal, simply by changing the dialogue and level intro/outro text.
