Wow, for some reason i kept coming back to play this. Nice idea! I think this game's concept is a great one, and it has a lot of potential! You should add different sorts of balls, maybe power-ups? Adjust the speeds, and the size of the arena?
Just ideas, but be sure to keep them coming, man! I loved it! 5/5
As a child, he was an aspiring artist.
As a teenager, he played the tuba.
He eventually became the first slug on TV.
Soon after, he opened up a small restaurant.
He later married a slug named Kathleen.
Together, they had 21 kids.
He died at the age of 84.
Pretty good place to start. Few things to add:
Mute button, pause button (in the pause menu could be quality, volume, main menu, etc.), disable the right-click menu completely, use different music, add upgrades for the towers, different kinds of towers, different difficulties, maybe a storyline, a cancel command (in case you choose a tower on accident), element resistances, flying enemies, and a sell button.
Besides those few things, I thought the game was entertaining. It's a defense game, so it is kind of hard to be creative. But the detail is great compared to most defense games. Try to add some element to the game that will make it unique - It will work.
Nice work, and good luck! 4/5
