Hey Heiden, thank you so much!
I think fleeing the first battle shouldn't break anything. But I haven't thought about it tbh xD
After planting the seeds you can talk to the skull again (use him like the other items lol). Then you can go into the forest with lots of creatures.
The blue screen is weird, the screensize should span over your screen with integer scaling + black border if needed. Thanks for mentioning that, i'll check out different solutions! I thought about just extending the screen with different zoom options in the future.
Thanks again for the feedback, I'm very happy that you had fun :)
