There are four powerups available to be purchased in the game and they randomly spawn in the arena, where you can collect them. In the sneak peek, you can see what two of the powerups looks like, the Instant Health and Shield powerup. The Instant Health as the name suggests, gives you an instant health boost. Upgrade the powerup in the shop so that the powerup gives more health. The Shield is a really handy powerup to be purchased. You'll be invincible for a short period of time, as a shield will cover you up from any dangerous attacks by the enemies. Again, upgrade it to increase the time you'll be safe by the shield.
Now, for the good news that is my excuse to the long delay... I can now tell, 100%, that the game will be released somewhere in the middle of December! Yep, my game is very, very close to get a release date. From the top of my head, I can think of a couple of little things I need to finish on and then I can start debugging and testing the game out to get rid of any bugs and make the game more playable. So, expect the release date and the name of the game to be announced next week!
