Speaking of maps – I guess it’s too late now, but I realized that Game Maker’s built-in map editor is total crap, and for my next project I’m building my own: )
On the animation front I have added one fluff cycle - a wobbling-on-the-edge animation if you send Iya sliding off a platform - it's pretty, but will rarely be seen. I have also started to expand the aerial pummel animation, which was previously nothing but a single lightning-fast punch repeated endlessly. It is now more along the lines of an all out Naruto-esque string of fist, knee and leg attacks - hopefully this will make the aerial juggling look more fun. Oh, and I began to correct the wall-pushing animation, as previously Iya lost about 25% of her size when pushing against things.
I finally added the third tileset - the first Catacomb location. It is currently rather rudimentary and is lacking ladders or any kind of ornamental flare or creepy necropolis parts (that I have planned for it), but with its cold gray walls and slightly iridescent background it adds a cool contrast to the game's other overly green areas. So far I only have one area-specific enemy for the catacombs - an indestructible floating eyeball that serves to impede vertical progress. The parallax layers for this set aren't finished yet.
My next logical step in development should probably be doing the opening area of the game - a modern city, so I can finally release a demo of LOI... let's see how that turns out.
