A quick update on what we're working on right now:
I just finished the first broad sweep of the engine and level editor's functionality. This means that we can start playing around with gameplay mechanics and fine-tuning our original vision to make sure that everything is as fun as it can be.
We'll be throwing together some prototype levels (maybe with videos!) and ironing out the logistical details that we didn't think about when planning.
We are about to start what I see as the "real" game development, where it's not just laying the groundwork in the engine, like I've been doing for the last several weeks, but actually working on the game itself.
More videos and screenshots soon to come.
