The controls make no sense at all, why would you use left and right click if your using the WASD for the menu and space bar for submit cheat / submit hold?
You should use n or k for enter/select and either k or m for back also the cheat button should be part of the UI and not a separate button tho I would suggest a control change option for anyone who wants to change them.
Other than the controls the game is a cool retro style west poker game so good job :)
