what an addictive game! congratulations on the work! It was amazing, at first I thought the game was just about connecting rubbish so it almost ended, but then I read the controls on the page and saw that by pressing E we could evolve and then I got hooked haha, I think I only have two criticisms for the game :
1 - In a future game, mention the controls within the game
2 - I think you used Game Maker to make this game, tip: when making the font, turn off the font's anti-aliasing so it will look less blurry and will match more with a pixel art game
