Thanks for trying the game! As for the value, personally I thought the day time limit benefitted the metroidvania format in that it makes it much harder to get lost, as you're always anchored home no matter how far out you get, as well as encouraging retreading old ground for collectables. I think the mechanic ultimately failed for most people this time around, but I think I can mitigate the bad and still reap the benefits with some changes.
Also, I already played your entry! I think it's actually my favorite out of what I played! Great work yourself!
