This might turn into a small rant so a small warning for you Benz and probably others, still appreciate all the work you've been putting into this game ^^
In my opinion, temporary boosts (implemented like this) don't benefit an idle game in any way, it is in a way the opposite of what i enjoy about idle games:
Feeling a constant progress however small it may be, while not having to be actively playing.
With the addition of junk and currently no way to passively gain it from other locations you are not currently at, I feel like it destroys what makes an idle game truly enjoyable.
It feels more of a chore to play, since obviously you want to be as efficient as possible, but now that forces you to always look at how much junk you are at or if you need to switch location since there is always junk from more than one location needed.
My suggestions would be:
Changing the current boosts into permanent upgrades without level cap, and having them only give a small increase per level to make them act as a small passive gain to your current stats.
or
Making the boosts only require junk from one location, so we can just farm the junk passively without having to switch location every 30-60 minutes.
AND (very important)
giving us a way to passively gain junk from other stages we are not at, for example through some sort of "junk chest" or other upgrades.
If these new features stay as they are, I can't see myself playing the game for much longer as I already feel tired from farming junk after just a few hours.
I hope you consider my suggestions and feedback, as I truly want this game to be as good and enjoyable as it can be.
And if others feel the same way as I do, I encourage you to upvote this post so it gains more attention 🙂
Thanks for reading this half rant half suggestion lol
i like that idea
