It surprised me how much fun I had it in! Level designing and later execute the plan was very cool. 
I had to get a hang of it with a few tries and didn't even realize you can knock them down with the doors, but beat it without it. 
Zack on stream thought building tower would be the only way, but I actually think doing a horizontal level is a lot better with arrows, meaning there can be different level designs there. 

Nice! I underestimated how fun it would be to spring traps on the "good guys" who are trying to save the princess. lol I really liked the mechanics, using A and D to activate either the left or the right trap within a room. And the level building aspect at the beginning was really cool. Really enjoyed it!

This had really clever game design, and was unique from the tower defense games I've played in the past! I enjoyed both the building and attacking phases, especially trying out the different types of traps. The death animation and sound effect also gave the game a great humourous touch!
