Thanks - I'm used to doing that and I'm familiar with the message and how to work around it, but this seems to be something different: it says the app is damaged and it's not possible to 'unlock' it from the security menu.
1. If you have between 20 and 25 currency in easy mode, the game brings up the "DEFEAT" popup, even though you can afford a greenhouse, since it only costs 20
2. Once I have chosen easy once, the costs are still reduced in later levels, even though the dropdown says "normal" when selecting the level.
Also: any tips on getting to stage 2 on mountain? I've gotten that far a couple of times, but expanding just costs so much that it's really easy to get into a state where it's impossible to proceed.
I feel like if I make a couple of moves which aren't perfect then I get into a frustratingly impossible situation and have to start over, which I feel like isn't the intention of the developer: it feels a bit more like a puzzle game where there are a small number of correct solutions, but only being able to rewind one step means that restarting is the only option.
To expand on mountain costs like 475: calcifier, wind turbine, excavator, pump, and then having at least 75 left to put down a new scrubber and greenhouse to scrape together some more money from the new location. It feels really hard to build up a pot that big.
