Just played through it. It was amazing!!!!!!
My favorite levels were the second Star level!!! It had so many features and cool moments! And also the Ice, the Harbor and the Final one!
The gameplay seems to be a nice mix of Super Mario 3D World with some Sonic elements, and I enjoyed it a lot!
Some suggestions: auto camera and maybe a custom draw distance perhaps? idk
Overall, I really recommend this game for anyone who likes a colorful 3D platformer!
