EDIT: V1.1 is now up.

I have been receiving quite a number of complains from non-QWERTY keyboard users as the game is completely unplayable on their non-QWERTY keyboard as well as several users who wish to have rebindable keys, so the next version V.1.1 will allow you to rebind the key configuration as you pleased.

Check this screenshot for the configuration: http://twinblazar.deviantart.com/art/Project-Dimentia-Bodhisattva-s-Configuration-547434757

You can rebind the key in the Pause Menu. Hit Tab to switch between combo list and keyboard configuration. On keyboard configuration page, hit SHIFT+C. You can now choose which key do you want to rebind with arrow key UP and DOWN. Simply press any key you wish to replace the old key with the new key. If you choose a key that is already used for another action, the game will play an error sound. Once you are satisfied with your control scheme, hit ESC. Then, resume game.

HOWEVER, the keys for cutscenes skipping and confirm/cancel on other occasions are still their default SHIFT+X and Z/ESC or Z/X respectively.

Also, Thanks to how save game works in this game, the keyboard's configuration is saved along with the game's saved data. This also effectively means they are not interchangeable between different save slots.

Unfortunately, if you change the configuration and you die before you reach a checkpoint, the game will reload the previous checkpoint, which contains the older configuration. Hopefully, checkpoints are plentiful enough such that this won't be much of an issue.

I will try to quadruple check for remaining possible errors and bugs before uploading this updated version. Sorry for the inconvenience and thank you for your patience. 

If any more bugs/glitches are found, please PM me.
