Always thrilling to get a playthrough from you, Meeka!
The family perished in a flying accident not long after the events of Proxima Centauri b--Dagger was never himself after that. I also originally meant to create a branching storyline, but it wasn't feasible within the timeframe. I may develop all this a little more in a later update.
The bug where it takes too long for the crawling enemies to kill you has been fixed, along with a few other subtler ones.
Thanks so much for checking it out! Were you using a Gameboy emulator? May I ask which one?
