Just a quick update, I've posted a new before I leave for California. It has a lot of fixes and some changes in response to the feedback I got. :)
The download links have both been updated! Thanks again for the feedback, it was a lot of help. Still a few issues need to be worked out, but this has a lot of fixes. And a new area too! Has the start of the newest area, you can play around in it a bit, but nothing too much there yet.
(I'm aware the keys hover over enemy health, I'll move that next time.) x_x
Edit: Forgot to mention this, if you want to keep your previous data, move the GameDetails.ini file over to the new demo and you'll have everything you had before. (Thanks for the comment.) :)
