Incredibly hard game. The idea is really good, but the box physics has to be improved.

Nice work for a game jam! I liked the game concept and the use of the theme. The physics on the boxes were a little bit funky, and the highest score I managed to get was 16.

Music and sound effects would be a nice addition.

The graphics are obviously simple, but I like the little exclamation marks you added to hint at the next box drops; a lot of games are missing this for important information off-screen and suffer because of it.

I liked the idea with this game, and maybe given a few more days I could be really good. 

A few notes: Firstly I liked the balancing mechanic and how it worked, However I felt that it was a bit harsh ending the game if one box touches the ground, given how fast they fall (may have 3 lives?) Also adding some sound and basic artwork would really improve the experience.

My best score was 6 lol xD

Can you add a mac port?
