Been giving it a go lately. Noticed three issues so far: - When "Bloom effect" is enabled under performance settings, some light sources glitch in a lightning/strobing fashion. This has happened to me mostly while shooting near Cthulhu statues from where enemies spawn, but it's also happened near fire as in the first few levels. - Vibration under control settings is disabled, yet my phone vibrates during events such as the Mech landing at the start of a level or when lightning strikes enemies, amongst others. - Performance has diminished with latest iOS version (16.7.7 on iPhone 8), as it stuttered a few times during some runs. Even though it's never been 100% smooth on my phone, just recently I noticed such behavior. Hopefully it's fixed, since it hasn't been updated in two years and you know how iOS updates tend to cause trouble in some games. ✌︎
