I am polishing the game and adding shops, changeable fire rates and firemodes.
But I was wondering If I should add levels to the game.?

Added health bar on top right corner. Score on left, new sprites and 2 new shot mode.
New shots are
Megabomb mode, can be unlocked when you have a score 1000.
and
Dualshot mode, can be unlocked by killing new enemy that spawns, this enemy is very rare and is found a score higher than 1000.
