This would be a very fitting entry for metroid vania month 😋
Amazing game, especially given the time frame! The graphics are beyond beatiful, I personally like the music and it's fitting to the games presentation.
Again, this game is suberly well made, which is why I would like to give some picky feedback. With a few tweeks you can easily extend this into something amazing!
- Movement could be snappier. With pixel games like this, movement is usually "snappy", it seems like you are using physics-based movement, so the character is "sliding" a bit. Also, personally I feel like the gravity value is too high. But that needs to be in sync with the rest of the game of course.
- Particles on respawn go crazy, they should calm down a bit
- Writing can be improved
All the best!
