This update is the first stepping stone of this year of development. It does not change the game drastically but adds a bit of extra content. The teleportation system will be expanded in the future, likely requiring the player to obtain specific resources to use. Still, since I wanted everyone to experience it, I did not complicate it any further.
List of new features:
1. Teleportation gates
2. Mesa biome (requires a fitting alien type in the future)
3. Black holes appearing in the Mesa biome
4. New weapon received through black holes
5. Difficulty options when creating a new game
List changes:
1. Swarm respawning temporarily disabled (due to being annoying)
Fixed bugs:
1. Various crashes caused by enemy targets becoming invalid
There might be more changes not listed here, but I have forgotten them since they were implemented a while ago.
With this update done, I will begin breaking up the game loop, trying to make it more purposeful and rewarding.

Thank you!
