WASD to move the character, going into doorways sends you through them. You can also hit the arrow keys to go through available doorways without touching them, and if you hold space and tap WASD you'll go through doors whether they exist or not. E to grab an item and Q to release it. M uses items.
Between x/y=1 and x/y=5 is in bounds (the location variable isn't shown by default), but you can go farther by using space+wasd. Out of bounds there's no doors (it's not worth generating them). The location variable has the 2 numbers stacked as 1 number (it used to be for ease of calculations, but I'm not sure If that code even exists anymore), so going past 100 or below 0 makes things weird. Sometimes you'll teleport to areas that don't exist or are miles away. Most bugs are relating to me being an idiot and switching numbers or messing up basic addition. I've fixed all the ones I know, comment any you find. Hit L to show and K to hide the location variable 1-9 show the locations of items, 0 hides all of them. If there's an item at location = 86, it means they tried to spawn at 11 and I banished them to the shadow realm for their crimes. Items: Sludgy Joe: Heals you. Max health is 200. Slows while healing. Boar Ball: Shoots boar spikes out in random directions. The only way to kill giant borbs, it slows you immensely while active. Speed Dalph: Slows you briefly before boosting your speed. Giant Borb: An invader of your dungeon! Use boar spikes to get rid of them. Follows you, and occasionally lunges or charges. A single borb can be very easy to run past, but watch out, multiple borbs can swarm you and tear through your health quickly. Borb Nest: Borbs that took home inside a boar ball, corrupting it forever. There will be many giant borbs nesting in the area.
