It's an interesting idea, but the upgrade costs scale up so quickly compared to the rate at which you get candies, so you end up looping through the same part for a long time before you can progress. Needs tweaking on the numbers, each stage shouldn't take exponentially longer to complete even with full interaction.
Hey!
Passed your game, and it's great! This reminds me of Evoland.
Would not post a screenshot, cause afraid of spoiling the experience for others. But I ended up with 197303 points.
I will agree with others, and actually it was something I planned to write before reading other comments. But required points after getting a bow and after getting enemies might be too big.
Anyway, it's a great entry. You did a lot!
Great job! :3
