An adventure where you try to collect kisses is a pretty cute and unusual concept. It's something that mostly appears in dating sims without any puzzles or games that are about more than just kisses e.g. Leisure Suit Larry. Aside from that, only the rather obscure Chulip comes to mind. So...interesting idea and cartridge here!
That being said, the actual gameplay, presentation, characters and puzzles are pretty basic and the game has no sound. It was submitted 27 days early, sooooo...there probably would have been time for that.
