The thing here is that not all phones who have 4gb of ram, let the application use that, some have it limited by system to like 1gb or 2gb but sadly our game has 4K textures and 3gb is necessary. I am not aware that this could be changed, it is usually a system setting.

When we lowered quality to 2K then a lot of people complained about the quality... and supporting 2 different versions was a nightmare. Over time this won't be an issue as new phones keep increasing minimal specs. We have 250+ animations, 2000+ flashbacks, over 1500+ emotions and 400+ poses, 60+ characters. Game is big, contains long hours of gameplay (just pure texts in all languages total are about 300-400 Mb big) also game runs on up to 120 FPS (on devices that support it) and primary platform is Desktop where 90% of our supporters are. Also keep in the record that we are doing MacOS, Linux, Android, Desktop (and older web version) as a very small team and it is not possible to test our game on every possible device. We are trying but no matter that, there can always be a device which won't work. Visit our Discord or SubscribeStar to learn more. Or choose preferably a desktop version.
