I agree another one for reptiles or any other kind of critter would be great. I love the system implemented, but it definately needs some tweeks, as to improve the battle system (all the bugs go after mine, even if they're literally walking over eachother to do so) and stats should be seen when buying/breeding. perhaps a tab on the screen that says the home stats that switches to the race/fight stats? also, in the next one, please implement a turn based move fight.
Personally I like the extra inventories. I use my(main char's) inventory as the main storage and sort out from there the few potions and useful weapons to various characters......when i overflow its going to be helpful to put loot into other characters....but, honestly i must applaud the developer for giving us so much inventory space per character. This is a great game.
