While testing the Kart Racer Game on the GPT-6 Astra launch page, I discovered a funny and reproducible bug.
If I rapidly press Space multiple times while driving, the kart starts gaining vertical movement and eventually flies above the track. 
Reproduction: Start the race → drive normally → rapidly press Space several times → kart becomes airborne.
I’ve attached screenshots showing the kart flying at around 189 km/h.
Not sure if this is an intentional physics interaction or a bug, but it seemed worth reporting. 
If anyone else can reproduce it, I’d be curious to know whether you’re seeing the same behavior.
