Gameplay-wise (and art-wise) it was really similar to Rogue-like or Camp Pinewood in the sense that you had a handful (maybe about 4?) of girls availbale to you whom you needed to convince/seduce first before before getting into some action.
The setting took place in a forest and if I'm not mistaken the objective was to survive in the wilderness by keeping each other warm for example. I may be wrong about that last part though.
The art as I mentioned was drawn by hand, I'm just not sure anymore whether it was drawn more like a manga or a western Cartoon.
Any help is highly appreciated!
