Damn the soundtrack on this game is excellent, props to the sound designer here!
I have a little bit of constructive feedback:
- make the player shoot a LOT more quickly! Make it so I can hold down the fire button, reduce the amount of damage per shot, increase the bullet speed, and it'll feel much better :)
- the art is decent, but I think a little more contrast is needed. Make the background nice and dark, that way all of the important visual elements (the player and the bullets) will "pop" more and they'll be much easier to see! I'd also lighten the enemy bullets :) you're using Unity, too, so there's no excuse for not installing the post processing package and adding bloom ;)
- more feedback! When the player gets hit, the screen should shake. When the enemy gets hit, they should flash white.
- the menu is straight up broken xD I'm pretty sure you've got something covering the buttons - I'd make your canvas scale mode set to "Scale With Screen Size", that way it'll always look the way it does in the editor :) I'd hazard a guess and say you've got it set to "constant pixel size", and in the build that has meant certain things have moved around and the button is being covered.
- I don't think there's an issue with the enemy bullet size, I think your issue is with your player's hitbox. Make it smaller than the visible bounds of the player! In most bullet hell games, you can be hit without dying on around 50-60% of the player sprite, with a small glowing bit in the centre that actually gets hit. This makes it feel like you had a "close shave", rather than thinking "ugh I'm sure I dodged that"
Other than that, though, it's a really good entry! I think you've got a fantastic little concept on your hands there, and with a little bit of polish I can see it being a game I come back to! Well done :D
Here's a video that illustrates a lot of what I was talking about:
