I'm hoping to have some sort of 'puff of smoke' effect when enemies and potions materialise, to draw attention to them. Making them glow is also a mighty fine suggestion.
I have got plans to add a special 'event' system once I've got everything else done, which will be like a short Choose Your Own Adventure style scenario. Depending on the decisions you make, it may influence whether the character gets a special power, gets moved forward, dies etc.
I'm also hoping to add a Special Skill that's specific to each character (eg, the Necromancer will be able to raise the dead, and the Assassin will be able to Backstab enemies).
Oh yes, and Troll Bridge shortcuts (kinda like the snake in Snakes and Ladders. Except the troll might eat you).
Before all that, I must sort out Sfx and visuals. I added lots of sounds today, and now have the joyous task of figuring out how to make them run in all browsers, and stop the game visuals from stuttering. Ah well, its all part of the merriment!
Cheers for your comments, chaps. Much obliged!
