Hello, i'm really glad to know they've fit well onto your game!
In fact, you don't even need to credit me, i've did those assets to use on my own games, but as these kind of things are pretty standart but consume a good amount of time creating all those models, i thought it could be helpful sharing with other people. But i would like to thank you for kindly adding me on your game's credits and also for your suggetion, i'll add those info on the zip file as soon as i have some time. I wish you all the best on your game development!
