So in addition to the awe-inspiring Aquaria, it looks like Aveyond 2 has been released as well. It's a shareware JRPG-style, uh, RPG, created using the RPGmaker engine for the PC. The original game was pretty damn good, and I can only assume that this game will provide similar enjoyment for old-school JRPG fans.
If nothing else, you should check out the demo.
