It was very funn but i recommend  that add more time between the changes sides cold or hot but in general is good idea you can explain more :)

I like how you got the theme into your game. Some hints at the start on what to do and what the controls are would be good. But I found it out and think the idea is good.

It was fun, you took really good advantage of the themes. I just wish it had a point counter or maybe a timer, it would go well with the infinite arcadey nature of the game. With some more obstacles, music/SFX and a point system it would've gone hard as a flash game back in the day

This is a really good idea, and I had some fun with it. The speed ramps up well, and it fits both themes perfectly. Maybe some more patterns would have been cool, but honestly there's not a lot to add to this game aside for polish. Great job!
