Thanks for the feedback!
When you say being able to select multiple items in the shop do you mean having two of the same? cause that is intended actually, you can have 2 solar panel gadgets for never running out of battery.
I'm considering making a tutorial level but I ran out of time for this DD.
Sometimes I failed the mission but I'm not sure how, I'm pretty sure time didn't run out. Yeah sorry about that, there was no alert for low battery (which it was probably that). 0.1.2 has this added as well as the fixing the spawn crab issue but you've probably moved on to other games. Thanks again.
