The music is really catchy. I found myself humming along, even if it does get repetitive after a while. The overall game design is charming too, though I’ll admit I’m biased since I’ve got a soft spot for pixel art. The game play follows a simple but solid concept that works well, and everything captures the Halloween vibe perfectly. The connection to the “uninvited guest” theme feels a bit weak though. I appreciate the effort you put into the intro, it sets the mood nicely, but it might benefit from being trimmed down a little, since the “angry kids” idea comes across quickly and the transition to the title could flow faster. All in all, a very good entry, especially impressive given you pulled it off in just about 15 hours.
