I really like your artstyle and color palette. I would have like to reach the end but I'll have to give up after 6 retries because of loosing interaction. I've got the pillow and try every door combination possible, but everytime I enter the yellow room the key drops and I can't seem to catch it or to drop the pillow. I've also tried to pick up the pillow before talking with Golde, but it's not possible so I cannot preemptively put the pillow down before hand. I'm sure there must be a way as some other people seemed to have managed it, but I couldn't :'(
Will try again once you publish the update.
Great job though, especially as a solo dev!
