Thanks a lot.
About graphics side. For fireball,ninja,knight etc. I used assets created by this person. : https://assetstore.unity.com/publishers/913
If you want you can check out this person's assets.
I also used assets for music, map etc. If anyone is interested for music : https://assetstore.unity.com/packages/audio/music/absolutely-free-music-4883
For map : Mine is quite different then the original but for anyone interested : https://assetstore.unity.com/packages/2d/environments/free-2d-cartoon-parallax-b...
Sorry if I forgot anyone but I think this is all the assets I used in this game.
