Hey! This game was so fun. I overlooked the simple graphics, which were still charming in their own way. My favorite feature was the sound effects! They were so funny and original.
The gameplay was pretty addicting and it took me just a little while to realize I had to replace the towers once the timer ran out. It was cool that I didn't have to wait until it ran out, which I also realized later :D but I had a blast. Later, I will try playing the game fully through.
Great job!
