thanks for your feedback, actually I tried some of these things, but as I am a newbie game dev, I failed for some of these and also added. This is my first game and game jam, I have learned a lot from this game jam and I think now I have improved my skills. And also special thanks for playing and giving me a good feedback.
thanks for the tutorial, actually when I started making this game I had nearly no knowledge of unity, yes I had used unreal engine and blender for making one game. But, unity was a new thing for me. Literally, I just followed tutorials of brackeys and other youtubers and tweaked them in my way. I also did some things wholy by myself. I learned so much that I think I can make better games in unity also.
