It's an interesting take on a turret defense game, and on the modifier. It took me a moment to figure out that some blocks could take multiple hits and that I could only control when the cannon fired.
There are definitely some glitches. One round ended with blocks on the screen, then the next round ended immediately after starting, then I got an inexplicable game over.
Unfortunately (or fortunately?) this one just doesn't really feel "so bad it's good" to me. The core gameplay concept is solid, and the game itself feels really more rough and barebones than that magical mix of goodbad. It needs sound, it could use better graphics and some UI polish, but it's not really bad, and certainly not in that weird, janky, magic way that defines "so bad it's good" in my mind.
