You can now download and play the very early Alpha version of Timmy's Adventure! Please keep in mind that this is an ALPHA release, which means there are a lot of things still missing, and I know they are missing, so no need to report that they are missing. The main structure is there and you can run around and get the idea of what to expect from a more finished release.
Click the link above to be taken to the download page on MediaFire. Currently, it's the only place I have it uploaded. If you have trouble let me know, and I'll see if I can't post a mirror link.
