Fun spin on the theme! Controls were simple enough, but it felt unbeatable. For me, somewhere around half HP the boss was too hard to get away from and death was inevitable. You got all the pieces into play though: UI, SFX, player controls, sprites, AI, etc. Everything a game needs made it in! I could see this becoming something similar to the game Rampage, where the "kaiju" builder tools tear down the city in unique ways and the builder has to defeat them to save the world. Good work!
