Patch V-12: new button with old function and old button with new function — icosi-do Steam update #103883

Another small patch polishing the interface for users of a single-button mouse: A "hint"/"undo" button has been added in the lower-left corner, which has the same function as the "X" key/button. In the tutorial, the "right arrow" button is now clickable in the hands-on parts of the tutorial with the puzzle. In this case, it has the same function as the escape key/button, i.e., it continues with the next step of the tutorial. The idea is that you can quickly click through the tutorial by repeatedly clicking that button. (It might also be less confusing than using the escape key/button to continue in the hands-on parts, but using the right arrow/"D" key to continue when text is presented.) Please let me know any further ideas to improve the interface for users of a single-button mouse, or other comments or feedback. Thanks!
