How does freezing spikes make them less harmful?

Theme implementation:

The theme is integrated into the gameplay; just the way I like it.

Special Feature Implementation:

There's a clock.

Fun Factor:

I think you should focus more on the controls in the future.

Gameplay:

There's some good potential in the puzzles.

Audio:

The first bleep caught me off-guard. Some music would have been appreciated.

Graphics:

I like the presentation. The menus look nice, which I think is a big plus.

This is a pretty neat game for your first game jam! While simple, the controls felt good and the theme was nicely implemented. I enjoyed playing it, great work! I think it would've been good if the theme was more explicitly communicated at the very start. Likewise with the clock, I'm not sure of the significance of it's role being a clock!
