Be A monster or A Monster?

Be A monster or A Monster?

It's a small player shooting game. The player will grow up when it comes into next round. There are 3 rounds in this game by now. At first the player born as a little dust, its default blood is 10 points and its default damage is 2 points. Each round its properties will multiply the round number (like in round2, the blood of the player will be 20 points and the damage is 4 points). There are enemies and energies in each round, your goal is to kill the enemies (by simply click the left mouse button) which will attack you and eat the energies (just touch the energies and you can eat it). Each round will add different enemies which have higher damages. Please note, there are 2 different type of energies, one is white one which values 1 point energy, another one is black energy which contains -1 point. The final energy point will result fate of you (monster or Monster). There is no good result or bad result, every result depends on you. You can play each round repeatly and the energy will still be calculated before the ending. 
Now, Good Luck!

Simple Instruction:
1.How to pass the round: go ahead touch the door which looks like a yellow light.
2.How to kill the enemy: click the left mouse button or pressing left ctrl button
