Other than new critters, I finally got around to adding in an animation for when the player attempts to pick up something that is too heavy to carry without the appropriate powerup. What's interesting is that I've known this has been missing for the better part of... what? A year? Most likely. It took about 30 minutes to throw into the engine, including art. You can see that in the screenshot below:
Other than that, it's business as usual: populating the game world. I'm getting closer to the end every day. This is like map building all over again: the end is always just in sight, but or some reason it takes so long to get there.
Ah yes, one last thing: I've added in a new gameplay element that will remain a secret for now. I can say this though: it will be optional and won't be required in order to "beat" the game. I can also say that this secret will mostly be kept a secret in the game, as well. You'll have to search harder than normal in order to find it. That is all!
