boring, no progression of people, they are not afraid of lightnings. too much revealed in skill tree (i couldn't understand a minute where the starting upgrades), but the idea is interesting!
Thanks for playing and taking the time to write, you made some really fair points. This is actually my first game project as a student, so hearing what works and what doesn't helps a ton. Glad you found the core idea interesting, and I'll keep these improvements in mind for future updates!
