Thanks for the comment and for playing.
I know that the controls are quite unique, but I believe it is for the better.
Long answer, but those were my thoughts when I was making the controls.
I tried to keep the depth of the menus as minimal as possible.
My priorities were that, interacting with the environment and accessing the inventory must be done with the less possible button presses.
So with that in mind, A became the interaction with the environment, B the Main Actions menu and C the Inventory.
Also, A is the confirm/select button in the Menus and B the cancel Button.
With those controls, there is no menu when you are searching for traps or secret doors (secret doors are not implemented yet).
You just press A and if there is no trap or items on the ground or an enemy in front of you or a door or a secret door, nothing will happen. No menu, no message etc.
This makes the gameplay much faster.
The Inventory cannot be accessed and from the Main Actions menu, cause this is the wrong (slow) way to pay.
For example, ending your turn is very important in this game, cause for example when you are approaching a new room or when your move may reveal new tiles of a room, the possibility of revealing a new enemy is very high. The best strategy is to walk slowly and have as much possible Action Points when a new enemy is revealed.
To walk slowly, you just do not spend all your AP (you end your turn). Move one block and then end your turn. So moving slow became UP -> B -> A.
Underneath the "End your Turn" are important actions that may exist or not exist in the menu. For example "Charge". If you can "Charge" then the option to Charge is there, if not the option is not. Putting this as a second option helps the eye to identify changes.
Last options to the Menus is the Special category of any character (Fighter does not have a special category). Cleric and Mage have Cast Spell, Thief will have his Sneak.
So the Special Category can be accessed very fast. B->UP->A and you are in the Spell List.
When you understand the controls, the gameplay becomes very fast, even for a turn based game.
Try playing the game by selecting to attack from the Action Menu and you will see how much faster it is right now, when you can just double tap the A button to do so.
I hope this clear things up, because I really believe that the controls are very good.
Edit: I changed the main game page. Hope this is more clear now.
Thanks.
