I do not know if I am the only one, but training the monsters has somehow a 2/3s cooldown, which makes it really annoying for me when having a high number of monsters.
Somehow, it does not happen when you milk them so I guess it can be some sort of pregnancy/stat calculation or the scene being rendered even when you choose the option not to.
I played to the point or my full day would be selecting my monsters, click, wait 2/3s, repeat. That made me being active around only 1/4 or 1/5 of my play time. Solving it would be great.
Also, have another way of transportation when moving physically would be cool, something like the mount you can spawn in WoW games. I took a long time to unlock teleportation portals and even then, some of the walking was a little annoying.
The mechanics could be something of a monster you train specially for it, I dunno.
But playing this game was really pleasant, and as a fan of the Breeding Season game, I felt the same spirit and possibilities.
Love the work put into, and playing it is really nice!
