While I enjoy the fast pace and social aspects of Aviator, I find Bustabit's simple design more appealing. Personally, the sound effects in Aviator can be distracting, but that might not be the case for everyone.
I know a guy who works in the Spribe team, he is a close friend of mine and I know from him that they put too much money into UI/UX research, design and development. A little secret shared, Aviator is created by a team that is employed by a casino that Paddy Power Betfair owns. One of the most talented guys for sure.
Btw wish as you do, be more unique and creative and don't forget to hype us a little when there is an ongoing development. I recently discovered AVIATRIX, a new crash game that it somewhat unique. They let you to build planes and soon they want to create an NFT marketplace. You build a plane and then sell it as an NFT. This is something new and cool. It can be an inspiration for you, check their ann thread-
