I love the game, because it's simple but it makes fun. But still, there are things, that I want to tell:
Theme Relevance:
Maybe I didn't understand, but the game has nothing about the theme rebirth, so I can't say anything until I get an explanation.
Gameplay:
The gameplay is very smooth and I love the game very much with the dash idea! But:
In full screen, the game isn't full screen, that had the reason, that you made the full screen function only by itch and not by unity, so unity don't fill the screen.
Also, I don't understand, how to defeat the ghost, because it isn't explained, so I wished more explanation and maybe an mini-tutorial, what would have images in-game.
There is a bug, where the (pink) enemies are not kill you, although you touch them without a dash. Only moving after the touch, the game works fine again.
Anyway, the gameplay is nice!
Artwork:
The artwork is simple and great, so I didn't see anything bad. Maybe particle effects or a screen shake by killing an enemy would be great, so you have more dash-feedback!
But, nice job!
Audio:
The dash, kill and lose sound is nice, but it would be great, if there are more sound, for example the enemy spawns or shoots, but this would be overload. An another idea would be different kill sounds depends, which enemy you killed. A simple, looping background music would be also great!
Anyway, the audio is nice, but it could be more.
In summary, the game is nice and simple, but it has more potential, if the game will be updated. So I wish you good success with your entry!
Best regards
