This is the first beta version of Zombie Slayer. 

I made a lot of improvements and additions to basically every aspect of the game.

The visuals look cleaner and theres no more screen jitter.

There's a new shopkeeper and you can talk with him. He is a weird robot and makes bad jokes. You also get the chance to rob him to get an highly overprized item, there is a bossfight planned when you do this.

I added a leveling system to have a sense of progression and to slowly introduce mechanics.

Added 3 new weapons and a new exploding enemy type.

Made a tutorial and explanations also when you hover over certain shop items there will be a descriptions what they do.

I also made a new song that plays when you reach level 10.

There where other smaller improvements like balancing.

The game is currently work in progress but feel free to try it and give feedback.
