Believe me when I say that I had the biggest, goofiest grin on throughout my several playthroughs ( had to make sure to get all endings ).
I really love the use of hand drawn assets ( and mouth noises ? ). I did the same in my game, though I evidently didn't stick to it as faithfully as you. Really makes me wanna try something like this myself.
Can't offer five starts at 'gameplay' but sure as hell can at 'enjoyment'.
