Thanks for playing and the detailed feedback!
The tutorial was designed to make the player understand the core concepts, so the levels are handcrafted in a puzzle-like manner. I guess this is misleading. The actual game is a strategy game. Should see how to not set incorrect expectations for the player.
Happy to know you liked the concept and tutorial.
Handcrafted levels would make this more of a puzzle game. I guess that's the kind of campaign you're suggesting. I could maybe have that as a game mode.
I'll see how to include fairies in the game :)
I'll work on balancing the shop and other elements like curses.
Will also work on balancing energy vs time.
In terms of the game being easy, are you talking about a particular grid density (low, medium, high), or all of them?
Yes, staying on the current cell by clicking on it is intentional.
Sure, will highlight the shop button more.
Your feedback is very valuable, and I hope to improve the game along these lines in the next iteration :)
