Hi there! Real sorry to hear that your GPU was needing to work super hard with the game. The game itself however doesn't need a mouse cursor after the main menu. The character just needs to be close to the object (e.g. Lock) and then you left click, no matter where it is. E to pick up objects, F to pick up animals, E to drop both, R to restart the level, and Mouse Left Click to open locks, knock down crow nests, or break planks. If you give it another shot, I hope that this helps! 😁 And if you ever get stuck, there's a gameplay video on the page. 😉 Sorry again!
