thanks for the feedback :D glad you liked the theme of the game and the plot.
The clicking was basically the killing of the enemy individually, that's how the game emphasises the theme as you take a more powerful weapon you have less health but you can kill them faster. If you take a less powerful weapon then you have more health but it will take longer to kill the enemy, that's why the spawn rate was adjusted because killing and clicking the individual enemys would be more difficult in the less powerful weapon than the more powerful weapon
Thanks a lot for your feedback once again :D
