You know what they say? If you ain't first, you're last! My first game I got last and my last game I got first!
After three plays I'd say I've seen all the game has to offer, which is perfectly fine. A minigame of sorts. There didn't seem to be much challenge or many interesting decisions to be made. I kinda just held spacebar, then dodged oil or tried to get pickups if I felt like it or could react in time. Tweaking the tension between using the speed boost and your engine heat could be an interesting iteration. Something dramatic like, if your engine overheats you immediately blow up, game over bud.
The speed boost mechanic being one of the major fun levers to pull on, some caution could be had around iterating on it. If you make it a more rare resource, for example, then it might blast you off to space when you do have or use some of it!
Had a bit of fun playing and a bit more analyzing the design. Keep up the great work!
