I love the aesthetic of the game! Being able to build next to the things I already built was something I didn't expect, and I really appreciate that mechanic. The movement is also quite nice and feels like it would be a Lego since the directional keys only turned the player rather than moved it in that direction. I think the main thing that wasn't mentioned is having the arrow (the one that points which way you're facing) visible no matter what. I noticed the arrow would be blocked by my turrets and such, so putting it on a different layer like UI would probably help. Other than that, really nice job!
