You definitely kept the song interesting with different sounds, Around 1:40 when we enter a new rhythm. I LOVE that part!!! The sound design is quite comedic. Some of the gestures are quite funny like the coin ding sample towards the end. I love what you did with it.
Your beginning melody line reminds of the song Popcorn haha. Then as the song carries on to your other lead synth at :25. I kind of lost Interest. the melody with that sound wasn't appealing in the high end. But I did like how it sounded in the mids. A spot where I noticed it was at 1:15-1:20. Where it plays the last few notes of the riff on the lower register.
However for that sound in particular..IMO I think you can make sounds that are far more better. You could also try a "call and response" method. Where two sounds are playing the same melody but they take turns doing so.
You also throw in a nice Egyptian feel at times which is nice. Especially with that sweet super saw at 1:24.
It's very well mixed in my speakers, just I think the sound design and parts of the arrangement fell flat for me.
But you throw in a lot of sounds and gestures which are really cool and kept me super interested and the usual "Pump" effect just helps enhance it. SO GREAT JOB!
(P.S. It's definitely louder :P)
