I played about 8 rounds but barely made it to the second level — the game is quite a challenge! I didn't quite catch how the 'Invincible' theme fits in since I felt very vulnerable, and I might have missed the mechanic that happens after death. However, the game feel is great! The shooting, sound effects, and overall impact of the attacks are very satisfying and pleasant to watch. It's a very interesting concept with a lot of potential for development. Great job!
