Very fun little game! I really like the art style and it already feels very polished.
The web version didn't run too well on my laptop (as expected). The native Linux version runs smoothly but it crashed once, soon after starting the race with this at end of the log:
closing closing ERROR: FATAL: Index p_index = 28 is out of bounds (size() = 28). at: get_m (./core/cowdata.h:144) - FATAL: Index p_index = 28 is out of bounds (size() = 28).
