Thanks a lot for playing it and spending time on the long reply!
And no, it was not only you. I also found it quite tedious & slow after the firsts days, but I realised last day and didn't want to make changes afraid of breaking my spaghetti code XD.
Yeah, in retrospective, a different mechanic to make the change quicker as either mouse or using arrows for select actions instead of moving the player would make everything much smoother. My focus went in other stuff that I didn't have experience(the rules mechanic and transition screens) and I didn't pay too much attention to other aspects that I made work on the first day, as the movement.
For future games I got that lesson learned for sure!
