Hey, glad you liked how it looked. I downloaded the asset pack called Eldorado on the Unity asset store, awesome free asset pack.
As for the issues with the aiming, I updated it so you should be able to adjust that: Blub Guardian - Now with Basic Ease-of-Use Options! - BLUB GUARDIAN by Soltar (itch.io)
Let me know if that helps.
The Blub won't eat unless it's hungry, which is defined by the hunger meter, you can put it to sleep if you want that to happen.
Idk if you read it, but there is a more comprehensive description of the mechanics if you scroll down on the game page.
Really appreciate you taking the time to play it :)
