Overall it's a great game and I love the themes. But one problem is that it's too glitchy and laggy. It doesn't have appropriate physics at all. It keeps flipping in its own position and blows up even when lands. But one suggestion is that since it has themes ,I think it'd be more cool and awesome if the bike had a color coming out from it,just like when Sonic runs a blue/cyan color comes from him. (And I'd like If the color changed accordingly to the theme as well).
