I reeaally liked how it felt to maneuver the kart! The upgrades were really fun too, it gave the game a bit of a roguelike feel even, making me wanna replay it to test it all out! The visuals were really nice too, and the blowing sand effect really added a lot to the feel!
A few criticisms: I thought that the camera would be nicer if it caught up to the player a bit faster, cos it was a bit hard to see if there were enemies in the direction I was going. Maybe it would also help to include arrows on the screen borders to indicate where there are enemies? I felt like the enemy movement was usually fine, but at some point I searched the whole stage like three times and then found an enemy stuck in a corner :b
I would also have liked a little bit more feedback both when dealing and taking damage, since it was a bit hard to judge what it was that hurt me sometimes. Overall however, I thought the game was really enjoyable!
