Does it happen with the paid version or with the free version of the game? Can you provide a screenshot for this bug, pls?

I usually test the game on a device with at least 6 Gb of RAM because it's pretty difficult to run lots of apps on your phone with the latest Android while having 4 Gb or less RAM. Speaking about improvements, the next update will feature a different type of compiler in Unity and version for ARM64 Android devices, so it should perform better, I guess. You can set the graphics quality to Low on your device and re-launch the app. Technically, Low graphics quality on Android means the usage of highly compressed textures in memory and it can help. Also, turn off post-processing and turn on the "ignore background bonus" flag in Settings, it will improve the performance of the game a lot.

Write your email used for itch purchase to me at darkexecutor2 (at) protonmail.com and I will send you a temporary Android build that might fix your issue. The fix will be rolled out during the next update, as I mentioned before in my previous posts.

Does it happen with the latest free Android version? Did you try to install both ARM64 and ARM v7 builds?

I checked the settings of the free demo, my bad, it's a bug on my side - it should be available, but I forgot to tick the proper checkbox. Thanks for pointing me to this bug, the public demo will be updated along with the next paid update, and this mission will be available there.

Can you provide a screenshot of which animation was broken and what animation was blank in the gallery?

Hi! .ZIP is the default format for an archive, try using the default Google Files app and unpack it, here is the instruction from Google on how to do it: https://support.google.com/files/answer/9048509?hl=en Other file manager apps should support this function as well
