How does your game fit the theme?
The game takes place in a planet, Mars, the objective is to collect as much coins as possible. But tornados spawn every 2 mins so you don't go outside the "base" for so long.

Tornados are the main objects that fit the theme.

Did you write all the code and made all the assets from scratch?
I've written everything from scratch. Except the player movement, I just copied some of the mechanics from my previous game "Rushing Square". But it was heavily modified.
