Hii! Awesome game, just two recommendations.
- You might want to change the sound effect when grabbing xp prisms. It is a little annoying, especially when you pick up many at once. Don’t make it sound like a glass bottle falling, but more like a simple "beep". That alone would make the experience more enjoyable.
- I don’t know if it’s very related to the invincibility theme. If you could add something that relates it more to that, it would be awesome. I assume that the connection to the theme is to eventually become invincible when having a lot of upgrades, but it would really help if you could make it more obvious.
I loved the art style, especially the movement animation of the character. Considering the time you took to make this, it’s impressive! Keep up the good work and have the best of luck.
