My plan going forward is making a system that is easily modified. a way to create preset levels, an entity system that can be used for decorations/doors/creatures, a text box and menu system that is meant to be very flexible in it's use. Effectively I hope to make a dungeon crawler template that I and others can use without having them all have very similar gameplay. It's something I have to do a bit of planning ahead for, but once it's done it could be a good tool for anyone who wants to make a dungeon crawler on the gba, which admittedly is a pretty niche audience lol.
