This pack reminded me of the last day on a beach vacation. It is about fun and excitement, but there are some more bittersweet moments in the harmonies and melodies. I think it would fit a casual game best, however, it would certainly also fit in with an adventure, Sci-fi, platformer, arcade, or light action game.
Layer 1 has the drums and rhythmic synth that provide a repetitive, but easy to listen to rhythm. Layer 2 has a couple of wonderful textures with a slightly out of tune synth providing some background and a plucky synth singing out the sparse melody. Layer 3 is also textural with a high string countermelody and a fuzzy, rhythmic synth more in the background.
The “Win” track loops and would be great for a win screen where players collect the spoils and/or experience points. The “Lose” track would be good for a danger or “game over” stinger.
