Thanks for the feedback! :) The controls were on purpose; I wanted the game to feel like you were riding a horse. I didn't want perfectly precise movement as I think it would harm the difficulty of the game, but in hindsight it should've been tighter controls overall.
The map was also finalized as a last-minute thing so there wasn't much time to see if it was too large or too small. I also think it was too large but too late to change, unfortunately.
