Hey, thanks for trying out my game :D
Lovely that you checked the up linux version as well.
Heh, not many players managed to reach that dimensional wizard, let alone kill him :) Definitely wanted to provide a lot more content but I barely managed the deadline, fixing a lot of other more urgent stuff.
Thank you for your kind words, yeah I am about presentation but I guess on a 7-day jam they took a bit more time than necessary :) Still, I am glad you liked it, I do like it a lot and will continue to work with it for certain.
Yeah, the "Jolt3d!" officially discontinued at around July 13, 2008.. You probably know already know my old website. In fact, I was working on it from like ~2000. These versions were using DirectX 9.0c and generally older tools. The new "Jolt3D!" engine is based exclusively on cross-platform code (that means OpenGL and a bunch of other libraries).
However, its a closed project at the moment, not publicly available. I am going to release the latest version of Jolt3D! along with the release of my other game The Darkness Below, which is also using the engine. However, its an "engine" in the "older" meaning of word, like it was used to be in 2000'; that means its pretty much a low-level API like SDL, nothing even close to Godot/Unity/Unreal editor based.
Thanks for the lovely comment and interest on my engine as well, loved it :)
