Here's a video showing what I've been working on the last few months, as you can see Gish's physics have changed quite a bit. We started out with physics similar to Gish 1, but we were running into the same limitations we had with the old model, so we decided to start over. The new model is made up of 128 particles which move independently and have an attraction to each other. The trick has been wrangling the particles to move as one blob, it's getting closer but still needs some work to feel like the original Gish. The cool thing is we can use the particles instead of a hit points, so Gish gets damaged by losing particles. This is good news for anyone who dropped too far in Gish 1 without holding jump and died.
We've also been working on the graphics, there's not much to show of that right now but we should have something in the next month or so.
Ramjets fan(s?): I've added a lot of new features and should have a new version up in early May.
