They are supposed to be aliens, but post apocaliptic pokemons works too! hahaha :D
Being compared to undertale in terms of storytelling in any way is quite a compliment for me, thanks!
Yeah I couldn't do more than just the intro. The way Pico-8 works is that the programming is limited to 8000 words to put it simply, and i hit that limit. So I have to make the code more efficient first in order to have space for more story.
Pico-8 has keys (X) and (O) which translates to Z/X unless you change it. I changed it now. Should have done it this way from the start. I will try to ramp up the complexity slowly to make the tutorial as minimal as possible.
Thanks for your feedback!
