I don't know if this game is still updated, it has been removed from all platforms.

The full game is not being updated. The lead developer abandoned the project. The demo here is a modified version of the forest level with new areas to explore, new enemies, and many other QOL enhancements, and was led by the composer for the full game (me). It serves to show what could have been possible.
