Could be an interesting game, and be enriched with more gameplay variety for a game show.
But brother/sister, focus on optimization. You don't need to care about anyone telling you, that your game looks abysmal. As along your art style is clear, things have unique details or you want to express something, as along your art has a direction; you don't care about the "graphics".
But man, really, i am tired of seeing games with abysmal optimization, terrible optimization that makes me want to close my pc and take a 2 hour walk and do 100 pushups in a day.
I don't care what engine you will pick but in the end, it is best to know the engine well. i hate both Unity and Unreal just because i see everyone, indies and AAA, making horrible optimizations that make the engines look terrible.
i can't play the game, when the obstacle course loads in, i don't know the controls and the FPS are on 1. Even when turning down all options.
Make options available to the players, show control input or a tutorial, like a simulation before the game show if you want to be immersive. Make the player being able to choose to disable those useless shadows if someone is desperate for FPS gain. Make sure the game is friendly to the player, the interface is friendly to the player
And make sure, you make good optimization. i don't understand how most modern games have terrible optimization; especially this game since it doesn't look demanding.
I do like the premise of it but if i can't play the game well and can't see the gameplay, i can't say it is good.
