I totally understand. There are a lot of problems that need to fix. I also know about the optimization problems. Honestly, the biggest challenge for me is not the audio, is the abilities for our team to communicate, solving problems and let my teammate to understand the workflow and use of github. However we only have 4 days to try to finish the game.
This game 's USP is about the timer, where there will be 2 sections for everyday and you have 3 days to finish the game. The enemy will appear in the second section of the timer. Yeah, my bad, the result of the build is looking terrible. Unreal Engine 5.8 does really require to spend a lot of time to optimize. Overall, thanks for your suggestions.
