Is my app decietful?

Hi : )

A week or two ago I released a game, “Red Defense” to the google play store.
It’s gotten lots of downloads, more than I hoped in fact. But 70% of people are returning the app
(I had no idea that was even possible).

I dont feel like my trailer or the summary are misleading at all, maybe the game is crashing?
But I don’t get any crash reports.

Has anyone ever had this happen to them? Would anyone mind trying the game and telling me if they felt like the game was unfairly portrayed in the trailer?

Here is the JGO page for the game (it has free promo codes if you have the time to try it)
