Quite a nice little game! Definitely very relaxing, and I used to be a big fan of games like diep.io so this was a cool throw back. Music and graphics were lovely, and I love to see great use of Unity's post processing stack!
Just some quick feedback of things I noticed while playing:
- The ui could have been turned to grey while regenerating and then turned back to white when it was full - In a fast paced game where you're focussed on the player like this, little UX things like that can go a long way so you can see the UI change in the corner of your eye!
- A menu / pause menu - Just a very quick one goes a long way in a game jam, getting thrown straight in on launch can sometimes be a bit jaring :)
- A slither.io style mini map would have been cool, to just see where you were any where you'd been
- Upgrades and stuff for adittional gameplay
- Health bar underneath the player? Again so you don't have to look to the corners for the UI
Overall a great little jam entry though, very well balanced and the player was just the perfect size I noticed!
I've recorded a quick video of the gameplay while I was playing, so if you want to take a look at how someone plays your game, feel free to take a look! :)
