insta max upgrading

[BubbleMax]

i got some bugg that makes me use all the money on one thing to upgrade but i can't use them on other things, i want to be able to use one upgrade at the time. Any way of doing that?

Sounds like your Shift-key is sticking.
A feature in the game is that holding Shift while pressing "Upgrade" (or while buying something) allows you to spend money to upgrade the targeted item to as high a level as that which you have funds for. (Many words to explain a small thing....)
Likewise, if you hold both ctrl and Shift, it allows you to downgrade stuff to lvl 1 while still keeping the item in it's slot.

I've had experiences with some games where the Shift-key ends up sticking while using the Steam overlay. If this is the cause of the issue, a simple re-press of your Shift-key should fix the issue.
If that doesn't fix it.... Do you have the "Sticky Keys" feature enabled on your computer? (Assuming you're on Windows.)

i'll be damned, thanks for the information TTRM :)

You're welcome. ;)

Edit: Just out of curiosity; What was the cause of your issue?

seems like the shift clicking, it might have locked it on shift after i pressed it, i just had to press it again to unlock that auto upgrading

That helped me too. Thanks
