First let me say, great game, it has potential an I can see it becoming quite addictive.
At this moment however there is one major issue for me, the performance.
Literally this game is running at 12 FPS for me and happily chugging along, but it's not nice to watch. Now, I am running it on a laptop but this laptop runs FarCry3 at high without much trouble, in fact, any game.
Judging from my graphics card's fan activity it's not that heavy on the CPU of the card so (and also taking into account my own game production experience) it seems like a graphical memory problem.
The supposed fix for the videocard drivers window does not work
The second minor issue I had was when I tried quitting the game, it crashed. Just hung, with a hidden error window only visible when you press ctrl+alt+delete and then to task manager and back to desktop.
Where is my save option? I collected some plants, distilled some medicine and then quit the game. Now when I go back in I'm on the shore again and all my progress is lost. If this is deliberate it's bad game design.
Keep on optimising and you have a winner!
