As you can see from mine i really like base defence games! And i loved the building idea . Only not being able to delete buildings was annoying for gameplay. But for 7 days, thats really nice work!
Thanks for playing my game. I don't know whether you have finished the tutorial but you can "delete" (deconstruct) buildings by selecting them while holding control. Though I have probably put that too far in the tutorial as most people seem to not get far enough to learn about that mechanic.
