Well done! I struggled with getting much further than a minute, but the game is just pure eye candy, the artist(s?) did such an amazing job. Audio is great too!
I had a few (quite minor issues), the start screen is a bit messed up on my ultrawide display (2560 x 1080), but its workable. My controller also start violently vibrating (even though I was playing on keyboard).
About the gameplay, the game feel is great. You really nailed the movement and it never felt like I had an unfair collision. I wish there would've been more too it. I played another game where the track slowly change from a circle to multiple circles, maybe something like that would've been cool.
Let's be real though, how much can we ask for in 4 days, you already made some thing that is frankly really impressive!
