Really good game, especially for a first. I HAVE ALOT of suggestion to improve the game. First and foremost. Add sorts of powerups. It can be no damage for 5 sec, a bomb, i dont know, anything that gives an advantage. You can also add a shop that can give healing to the wall, more shots per seconds for a period of time, more money gain yk anything that adds more variety. Also you could make it so that it costs ALOT of money but you can add extra slots for more turrets. A simple but fun game. Also the resolution is weird. Its not in fullscreen nor i can see everything, that should be a mendatory fix. Overall good game fire!
