Thanks for the full in depth descriptive feedback!
I am trying my best to come up with ways to spice up the content.
You made very good points and I will consider them all,
About the Shop&Mechanics - it sure can be very good, I just need to be careful with scope creep, this is a small playtest after all, but I will think about it!
for the levels and sword, it was a quick way to give the player a progression of new enemies + cursor AOE gets bigger + higher base dmg + crit + max enemies hit in single click is increased.
Thanks again for you very kind words and suggestions,
I will do my best I promise :)
