Not bad
Theme implementation:
You're in a thermometer, so there's definitely some temperature shenigans happening.
Special Feature Implementation:
Well, you hear a clock ticking and there's a timer, so I guess it's there.
Fun Factor:
A bit repetitive, but that's ok.
Gameplay:
There's a bit of a glaring oversight where you can just keep jumping as long as you're touching the ceiling. I guess it checks whether you're grounded by seeing if you're touching a ground tile, which is a flawed system for that very reason.
Audio:
Very repetitive. Some music would have been nice.
Graphics:
Simple, but effective. The main problem is I think the screen shake is way too aggressive.
