This is nice, reminds me of those marble race videos on youtube back in the early 2010's while I didn't get too far in I can say I liked what I saw, the rainbow trails looked nice, but the time flow buttons didn't seem to work that much at effecting the balls.

Cool! I like the concept, a creative idea. A few suggestions I have are to shorten the trail, as I feel its a bit too long. You could also improve the visuals by maybe adding post-processing for a bit more of an effect. Overall, good job.

Wow, intresting game, i like it)

I really enjoyed it! For your first jam I think your game has a unique concept. I find this game rather short and also it lacks in the visuals category but all in all, Well Done!

Hope Everyone enjoys my first game!
