That was quite fun. It didn't take me long to get all the endings and the overall vibe of flirting didn't come off too impulsive or desperate (mostly). I liked how lively the characters looks and the art style is, ironic considering this is a Halloween game. The music almost made me go to sleep as well but in a good way since it has similar vibes to that one Nichijou ending.
In any case, good job.
