You should try Vampire Survivors for iOS. I only played once and I know I’m going to love it. I don’t understand why this game is free. It’s one of the most popular titles for Steam Deck, and it costs £3.99 on Steam. IAP/ads are likely going to appear once the iOS port is popular. Disabled App Store updates to save this gem. This is the first time in my life I see such a good product, free, with no ads and offline play. 🎮
The game has ads after all. But viewing them is optional as a price for reviewing your character. I am not sure if PC and Mac have the same mechanics, but I am not planning to press on the watch ad button.
