My first project, made >3 years ago... I've progressed a 'little' bit since then...
In the words of my 9-year-old self: "when you start, it is arrow keys to move. first go home and get money from the safe. then, go to the store and buy a sword. it is space to use it. then go towards the bat and press space to kill it. you will get some gold. DON'T BUY A BOW IT DOESNT ALWAYS WORK! to respawn the bat go in your house and come out again. when you get 50 gold, go to the road on the right. touch the money booth. pay 50. kill the dragon. then go on the road to the left. when you've killed the dragon go to the bottom road. the guard will say come in and if you want to go in the castle touch the gate. instructions are included from then on."
