Frog tower defense

For This unity game, I made for a school project, I decided to make a variation on the typical tower defense formula. Tower defense is one of my favourite video game genres and I had a good idea for how to differentiate this tower defense game from the others. I made all the sprite artwork myself in asesprite, but the thing I'm most proud of in this game is the enemy movement. Put simply, every enemy knows of every tile where they can change direction, when it touches one of these points it checks every other tile ajacent to it, picks a random one, and makes that the new target destination. When the enemy touches a winning point, you get cash, and when it touches a losing point, you lose lives. The goal of the game is to direct them away from one exit, and lead them to the other exit. I made this visual sheet to hopefully explain it clearer if it isn't already.
