I was surprised to see such fleshed out systems in a gamejam entry, so great first impression. This is also a very different interpretation of the swap theme so points for creativity. I do wish there was more strategy and player agency over swapping like being able to see your opponents loadout and seeing more parts come with weighted drawbacks that change your build.
During all my races with the "Press A to Boost", I could not feel any difference in speed and somehow got perfect timing on every one. This is the equivalent of Jockey Race games which I can definitely enjoy as an idle game if the race visuals had more flair. Regardless this left me impressed!
