**Updates**
Version 1.1:
-The game now saves every 5 waves
-Added New Game+ mode.
This game starts easy, but if you're not careful in your upgrade and purchase strategies, you'll soon find yourself overwhelmed.
Reach wave 40 to see all 5 different enemies.
This is the first release version of the game. I've done plenty of testing, but if you find a bug or think the game could benefit from a new feature, please let me know!
Tips:
-If you find the game lagging, try disabling Gore and/or Casings
-Invest early in the Fast Learner and Lucky abilities.
-Jumping is key to survival. Unlock/Upgrade the Multi-Jump ability when things start to get tough.
-Unlocking perks by completing achievements is an important strategy to beating the game.
-Sometimes a new weapon won't be as powerful as one you've already upgraded right away. However, investing in upgrades for new weapons will quickly result in a better weapon.
