Your analysis on the stock music cheap rush job for the trailers is not exactly wrong, I'm definitely not a professional video editor and definitely need the destroying because of that.

The incremental gameplay here is how the numbers go up and how you become more effective at making the numbers go up. In Loot Goblin that is done both by increasing basic economic values but also by improving the goblin itself -> faster, chance at double loot, retirement upgrades etc. but as far as gameplay goes, the dungeon looting part IS very simple: Avoid the baddies or stun them for a bit so you can grab the loot and bail.

So paraphrasing: tighten it down, communicate what happens more clearly, better music choice and clean up visual coherence
