[GAMING 🕹] Are you ready to enter the crypto arena? Beta tester wanted !

[Blockito]

We are a small indie studio making a game we hope will speak to the Bitcoin generation ! Because every revolution has its game.
We need some crypto enthousiast beta testers to help us shape the game that's why I'm writing here. No rewards, just fun.

Just finished watching its demo and I have a concern in regards to the mining part of it... Apart from validating a transaction, is it going to keep using our device's resources in the background, even after receiving the reward or it stops as soon as we click on the validate button?
- Does the following "tweet" mean it's not just for mobile devices ^{[not sure if that's the back-end part or that's actually how a part of the game is while accessing it with a computer]}?
