This is a cool idea and is actually pretty similar to the platformer that I made. The controls felt a tad sluggish and I kept dying when trying to defuse the enemies because they appeared too close, but it was a neat game!

Very cool idea, the aiming isn't very accurate and when you defuse the enemies appear to close, but it's a good game.

I really like the idea ^^ It could become a very fun game.

There's a few issue you can improve on:

The buttons in the menu selection aren't working properly. My guess is that the hit box of select level is bigger than the sprite and covers the other buttons.

The aiming doesn't follow the mouse correctly. I know it's very difficult to get it right but it's frustrating. I can try to help you understand how to fix it if you want.

The hitbox of the ennemies are too big. In a game, you always want your ennemies hitbox to be smaller than the model it's affixed to. Otherwise the collision won't feel fair to the player.

When I hit play the game, I got thrown to level 4 for some reason.

Add maybe an arrow to indicate where the ennemi is going to go after seperating 

Hope it was helpfull ^^ 

Really good game, but you should make a tutorial in the beginning but you should also make the tutorial optional if you add one.

Fun game. The instructions are hard to read.
