About this project

The is a game simulating a boss battle. You use the buttons to determine your attacks and change between screens. Your opponent (a demon) attacks using a random algorithm.

I decided to make this as it's a fun idea and a throwback to old & retro videogames such as the original Pokemon and Super Mario games.

The choices for attacks are:- The Blade Of Isin (2 Damage)- The Staff Of Kanas (1 Damage, +1 Attack)- The Spell Of Tories (0 Damage, +2 Attack)- The Potion Of Meseus (0 Damage, +2 Health)Good Luck & Have Fun!
