Very cool! I admittedly didn't read the comments first and know there was a tutorial and didn't know what I was doing. So I went back and played it again and noticed the tutorial on the left side kind of behind the player. I can see people have been having a good time stacking blocks under the turret, lol. I like how the tower defense unfolds right in front of you, it's very engaging! I would love to somehow interact with the planes when they fly in front of my face. If you update it in the future, maybe allow the player to bang on them or bump them a little just for show, not for changing gameplay.
