This is really good. I really wish i could learn how to make my own idle game like this. Was it really easy to make this or was it really difficult to make this?
I think you should add a card where if your away you can have Auto Magnet on so that way. When your idling, And away, You can still collect drops. But make this card a Rare to find card.
I think you should add a music player or a video player or something that you can like look stuff up through a youtube like search engine and choose a song and play it during you playing this. And have a option for loop. But if you can't do this, No hard feelings dude.
Single/multiplayer missions would be nice. Like for single it's 50 xp and like in multiplayer it would who got the most kills to get 100 xp. and the rest would get 30. Or have a ranking system where 1st is 100 2nd is 75 3rd is 60 and the rest is 40
Maybe use the actual Youtube for that? More features, no extra loading, no worries about copyright.
