- If the player starts with more than 5 exp, the level will not updated until the player gains some exp
- The current atk/def algorithm needs work, a simple one has currently been implemented as a trial
- Position of merchant is not checked if it has a conflict with other merchants/players
- There is a chance that if the number of entities to be generated is directly equal to that of the mapsize, and the last
entity to be generated is a threat, and the last tile without an entity is the magical potion, game could infinite loop (unconfirmed)
- All these will be fixed in a future update

Version 0.3.1 Code Patch

--------------------------------------------------
Description: Small patch with a few minor fixes,
mostly not intended to add or change features,
focuses on rebuilding some parts of the game with

--------------------------------------------------
Description: Patch that revises the main flow of the
game. Instead of switching back and forth between

and the time taken for each player's move can be adjusted

- Changes: Game is now executed by running through in-game time in pre-defined (defualt 0.25days) time intervals,
then deciding if anything is to be executed in this time
