I'm not sure how it really fits the theme, but the game runs great and is quite addictive. The only downside would be the camera which is often upside down or stuck somewhere.
Looks good ! It's really hard though, especially once the second pattern starts. I didn't get if I was damaging the boss or not ? The introduction is also nicely done.
Well done ! It took some time to get what each turret did, but once I figured it out it was quite fun. Having more information when placing turrets / seeing the ennemies life bar could easily improve the game.
