Glad to see this is still alive! The immersive mode looks neat and I will never say no to a flowchart in a VN. Especially in a sandbox one. Looking forward to the next update! But take your time, the increase in quality is worth a longer wait.
Edit: I personally don't care about a few extra MB if it adds a nice feature to the game. 40 MB are nothing nowadays tbh and the game is comparatively small (in terms of file size) anyways.
You are aware that devs can request for bigger uploads limits than 2GB if they can explain why their game is bigger? The biggest issue with going past 2GB is Andriod due to APK file size limits.
