Thank you for the feedback !
The main goal was to create a choice between :
- "greed" another wave with the current morph, even if this isnt the most appropriate in order to earn golds + unlock current permanent boost
And
- just open the box, to look at the content, probably buy something, and swap morph to adapt to the current wave
You can noticed that the crystal you use on the shop lose the "$" logo on it, but yeah not enough explicit at first obviously.
