Thanks for sharing your thoughts. There's no ability to rebind controls -- these settings are leftovers from the standard Unity configuration.
The waiting mechanic was designed to allow the player to replenish energy in combat, but also rest in the dungeon while risking a random encounter. However, since random encounters never made it into the game due to lack of time, it ended up feeling like 'debug cheat' indeed.
As for the UI -- the visualization for attack types and targeting modes was cut to stay on schedule. Initially, you'd have a list of body parts of each target and their status and hit probability to figure out the best sequence of actions to deal with each enemy type.
