My game for the first Game Makers Tool Kit Game Jam and also my first game jam.  

Play as a gladiator who has only one shield to defend himself. But it's not just a simple shield, you can repel enemy attacks and perform pushes. 

The idea is to use defense as the main weapon. When defending from an attack, the attack is repelled and special bar increases. The special attack is a powerful push that throws enemies away and together can come rewards as an extra life.  Jam submission or https://romulosan.itch.io/shieldnator
