Stating my bias upfront: I have a speedrunner streak, nothing insane, but I do get a lot of satisfaction grinding my times down in certain games.
This game easily scratches that itch (and a lap difference each lap would be a very cool feature to help know if I am on pace).
I second the addition of a minimap or turn indicator. In a game like this, players like me will play the circuit over and over again until it is memorized anyways, so unless there is some sort of procedural circuit generation in the future (or something else), I am not sure what testing the player's ability to sight-read is adding other than a few run off the road moments on the player's first couple times with the map?
If you want to keep the skill to react to the unknown as a part of the game, you could also consider adding semi-random road-hazards or something?
Very fun regardless. The drifting feels very good, pretty forgiving with a good slide-to-overdrift ratio for me. And it is always very interesting to peak into the developers thought-process. <3
