The visuals are super appealing! I liked the cardboards cutout styles and the bright environment. It was quite charming. There were some times where I wanted to go to the center lane but ended up at the front lane instead. Maybe the colour of the tile indicator can change when you hover over it.
The card varieties were nice, I liked the laser one since I can get multiple slugs. It allowed for more strategy to figure out ways to get ahead of the others or slow them down. I did find it a bit hard to catch up to the other slugs but I'm also not the best at strategy. I ended up a few tiles behind first so I think I'd eventually get a win with a couple more races.
A super minor thing was when you had a larger hand, the right most card's text would be partially hidden by the end turn button. It was a super minor issue and didn't affect my gameplay much.
Overall, super well done! Great job!! On a side note, your itch page looks super pretty! I liked the moving elements :D
