I haven't experienced any crashes. Did find a few bugs though. In goblin and orc village there's beds you can use when you have a monster with you but the game gets stuck in a black screen.
EDIT: I'm gonna write some walkthroughish stuff here.
The game is pretty simple. In the beginning the only "friendly" monster is the pig. Have "fun" with a monster and he will follow you until you give birth. The monster you give birth to will have a chance to get a little bit better stats and some new skills. To make stronger monsters make a few babies, check which one has the best stats and/or most skills and have sex with him. Basicly keep fucking the newest child.
Next how to get new monsters: You attack their base and beat them with the help of your strongest monster. After that you are free to enter their base without obstructions and make babies with them.
All the monsters have an element which defines what magic they can use and what magic they are weak against.
Pig and Orc: Earth
Fairy: Wind
Snail and Tentacle: Water
Goblin and Minotaur: Fire
I'm not sure how the magic weakness stuff works exactly because I was able to do about 300 damage with Pigs earth spells on Snails but Snails water magic didn't seem to do jack shit to all the other monsters. I was able to clear most of the monster bases with the help of Pig #20 because they get pretty good defense and hp.
Also good to know is that each base has an unmoving monster near the entrance that sell nuts and some other stuff in exchange for... babies! (you must not have a monster tagging along to do this) The cost of items raises every time you buy them (3 babies for one apple?!?!).
HINT: The pig outside the pig cave sells a map for 3 babies I think. The map allows you to move faster between the bases you have conquered.
All in all you just go around breeding strong enough monsters so that you can conquer all the monster bases. While you're exploring you might find some ruins that have incredibly tough boss monsters inside them. I've found 4 and I haven't beaten any of them yet. I'm guessing the goal is to beat all 4 of them to get to the final part of the game.
Oh yeah and btw, the monsters seem to die off over time from old age or something. I'm not sure if they can go extinct but be careful while making babies, don't make a hundred babies for one race at a time.
*wink wink*
