Troubleshooting Guidelines for Mobile Play

Sharing my experience. After publishing, I found a challenge for developing a web game: Even though it was reported that the game is not suitable for devices, the intention is for everyone to be able to play.

1. Screen size that does not support portrait orientation - Even though in Godot, both the UI and the window settings are selected to be flexible, the real problem is the main camera, which must set the aspect to keep width instead of the normal keep high.

2. I tried playing via the web with an iPhone device. It turned out that the effects during spawning and explosions did not work. - I will try to use mesh animation instead of using particles, maybe animate from blender and export as glb.

3. The qiut button is useless if published by playing via browser - Cut it out for web games.

4. Improve the ui to be beautiful - If I am too lazy to do it myself, I may find a ready-made pack 😅. 

Additionally, at first I found a problem with the texture map not working. In reddit, they told me to reimport by changing the VRAM compression to Lossy, which worked.
