I think you already know how much I liked this game earlier from the stream. It has a weird surreal quality to it that is awesome, and the original spritework is extremely consistent and reminds me of an old GBA or Super Nintendo type of game. Definitely some Yume Nikki vibes and other stuff in that genre. You guys did a wonderful job, and playing it through to the end was absolutely worth it. I almost wish the time lasted a bit longer because I definitely would not mind spending more time in this world you guys made.
I think my only complaints relate to collision. There's a lot of wonky collision that tripped me up in a couple places, probably especially during the hedge maze area. Fitting into those corridors was so precise and lag I was experiencing made it hard sometimes to squeeze through it... especially fast enough to complete some of the challenges. I feel like this would immediately be improved by either reducing the size of the player hitbox a little (gives some margin of error) or by making it a circular shape and using move_and_slide() so even if you're a little off you'll sorta slip into place.
And sorta related to collision was that I noticed some objects, like the levers and the items you are searching for, have weirdly and awfully specific areas where you're allowed to interact with it even though you seem to be looking straight at it. But then other times, like with certain doors, I can be standing several tiles away and still interact with it.
But those complaints are very minor compared to my overall impression of this game. I really want to see you guys do more and hopefully do a full game in this kind of style with more time to polish it. You got the mood just right, and the heart of the story definitely comes through- it's easy to tell you put a lot of love into this.
