I really like the tower placing mechanic! very smart way to get around the tough 2 button limitation!
the pixel art is great and i love this little wizard dude really fits the game well.
other people have mentioned the wave 1 difficulty, and i agree. maybe this could be solved by just making the enemy hitboxes a little bigger? it was a little frustrating having the bullets thread the needle between two enemies and taking a load of dmg because of it.
