Fun game! Loved the creativity and how you took the theme. I tryharded and went into epic gamer mode but still could not beat it D:
Music was sick, loved the CRT Shader and all the other post processing.
However, when it was my first time playing, it wasn't clear what I had to do (since I couldn't beat the shield thing). Maybe add something that explains that you have to pass shield thing to fight the boss? (You might have idk - i suck so i couldnt even beat the tutorial :P)
Overall, I loved the game! Well done!
