The casino website display is not too luxurious and lots of images, plus using a black website template makes it more shady, I think your website is also very simple and also easy to access in my mobile browser, welcome to the forum
i won't judge them early. but it may be true that you may get a different notion when you browse their site as they may be using a common template of a casino which usually gets abandoned without notice. if they will improve their interface or maybe add their gambling license later on, it may add some kind of credibility to the site, but atm, if you're not sure about this site, then just play small or don't deposit. as simple as that.
At the moment many people are skeptical to try a new casino especially if they see the owner don't do any much effort to build their site. And maybe to many people doesn't see them yet worth to try because first impression is really important to new clients. Maybe best for now to create some improvement to impress people here so that they can convince people to test what they can offer.
