I've been playing with the 32-bit Linux client after discovering that it doesn't suffer from the failed assertion of the 64-bit client, and must congratulate you on creating such a fun and addictive game. I've found a couple of more bugs though, although not very serious ones. 1) The "disable click-to-move" option isn't saved in the configuration file, so it has to be turned on everytime you start the game. There's no entry for the option in config.xml. 2) You can't open chests by walking into them, but if you pick something up with the cursor you suddenly can. The item in the chest will then replace the item you hold with the cursor, and that item you previously held with the cursor simply disappears. 3) Monsters seems to sometimes spawn on top of each other. This means that you might see only one monster while it's actually several monsters, and when you start to fight "it" they split and suddenly you're fighting a whole group of monsters. 4) I think this has already been reported, but Eelys sometimes stack, and sometimes appear out of water in zoos.
I found another bug, a way of walking into monsters. You stand one tile away from a monster that is walking toward you, i.e. so that you have one tile between yourself and the monster. If you then press space and quickly walk toward the monster, both you and the monster will take a step towards each other and end up on the same tile. It seems that the game checks if the tile is occupied before the monster has reached it. This is with the 64-bit fixed Linux client from your blog.
