Can fully refund cost of heroes while still fully upgraded

[boingbloing]

1. Max out a hero
2. play next stage while the same hero is still selected
3. restart level
4. sell hero down to lvl 0

the hero doesn't lose levels even though you get fully refunded, allowing you to easily max out every hero before even reaching the turbo levels

I've tested this and every single hero gives their full power/effect

my coin count after finishing turbo mode, every hero maxed out

sry for all updates, new to github

Update: also works in endless
Update: if you have all heroes maxed out by doing the above you can press reset all to get a tonne of coins (with nothing to spend it on) resulting in heavy lag/fps drops in the hero screen (not ingame what i can tell).

if my specs matters im on galaxy a54 5g

Interesting exploit. Thanks for pointing that out!
