I might have just created an account here to comment on this game and I've been playing for a few hours now as I enjoy this very. So far I think I've gotten the secret intro (if the poem is that) and the endings:
1 2 3 4 5 6 9 10 11 12 13
So like 11/15 endings plus what I think is a secret ending (slapbo) and I would like to know if anyone could help me with the remaining endings?
