Thanks for the reply!
I understand what you mean — selecting, modifying them to fit the game, and putting everything together is still real work, and a lot of devs do it that way.
But it still refers to the original creators of the assets, so I think it wouldn’t really be accurate to say “built” them as a fact. It’s more like you modified and integrated them into the game.
If most of the assets are yours, maybe just mention something like "most assets created by me", or highlight that the programming, game design, and development were all done solo, working late nights.
The quote feels a bit misleading yeah, but glad you’re open to changing it! :)
Looking forward to your future games, this one already feels really good!
