Design an eye-catching flyer for Escape Route app

Escape Route

An app for users to search, find, and track escape rooms.
It can be downloaded from the iOS App Store, and the Google Play Store. The website is escaperouteapp.com

We want a postcard (front and back) designed that can be placed in various escape rooms around the country to easily convey that this new app exists.

The idea is for it to be clean, attractive, easy to read, and convey the unique selling propositions of the app.

The postcard should be in standard size (I'm thinking something like 4"x6")

Here's some of the info we'd like included on the flyer:

Make escape room searching great again.

The ONLY app devoted entirely to escape rooms.

I've attached some concept flyers I threw together myself. I'm obviously not a designer, but maybe they help you spark an idea.

I've also attached a psd of our logo to use in the flyer.

Please be as creative as necessary, as we want this to portray professionalism and capture attention.
