This game reminded me of pocket tanks I used to play as a kid so I was excited to see all the different types of tanks. At first there were very few ads, maybe one after every 2-3 battles. But shortly after upgrading my first tank once, I couldn’t do anything without an ad. It started off after every battle I had to watch a short 5 second clip before I could claim my rewards but it quickly became I had to watch several short ads or one long one I couldn’t skip before I could collect my rewards, before I could enter any type of battle, before I could pick my tank type.
It was very frustrating, so I spent a few to remove ads, but now all it does is say video unavailable and I have to sit at a black screen for 30seconds and then I still can’t collect rewards. Or I have to restart the app.
I’ve contacted the developer for a refund.
