I'm not sure if anyone is still around, but I'm still grinding away at this for about an hour or so a day, and have made some good progress.
- Create fire (damages player)
- Created snakes (enemy, damages player)
- Created first aid kits (increases health)
- Created quicksand (stops player movement for a few seconds, needs improvement)
- Other minor gameplay modifications
- Completed Level 2 (fire and snakes)
- Squashed some bugs, created new bugs
I'm planning to create vultures next, then build Level 3 and 4.
Here's a screenshot from level 2...
