Looks like a great learning project!
- Innovation – The bouncing shield mechanic has been in other games, but it is done well here!
- Fun – It is fun bouncing away the bullets. I wish the controls felt a bit more like a space ship with some acceleration and deceleration.
- Graphics – Looks like Microsoft paint prototype art, but it is kind of charming hehe. If your bad at art I would at least get some cc0 free sprite art and recolor it / edit it to make it your own or for reference practice. A parallax star background would look great too.
- Audio –It is cool how the slow-mo changes the music too~
- Polish – Not much polish yet, but it is a good start. Things need feedback too, example: the shield could scale up a little when bouncing a bullet, some movement particles on the ship, some trails on the bullets, some screen shake, etc.
Great job making the game, keep at it! Please check out my game if you like Metroidvanias or platformers :D
