Closed Upon Opening – Pixel Art Camera Review

I downloaded the app and upon opening it for the first time I was able to click allow camera access before it closed on me. I have since force closed it, re-opened it, and even restarted my phone and re-opened numerous times to no avail. I expect I would like this app but without being able to actually use it, I can't review the quality of its features. IOS Version is 10.3.3 on iPhone 5c
