The amount of time I spent on this... i'm not telling... but heres 5* for fun lol.
When i learnt some weapons could be double-wielded... man.
I can't believe this was made by 1 person in 10 days, you are a beast. From the very starting intro, I thought of FF before the words even unfolded. Completely nailed the theme with the retro music and logo design. Then it became "Rise of Shield Hero" with the portals and the unlikely heros that were summoned. Great humor. The attention to detail is insane. Each hero has an entrance that matched its type (bunny bounces).
An extremely compelling idle battler. Well done good sir!
