Fairly solid game. The art despite being fairly crude has a charm to it.
I think the main thing missing is a lot of I'm assuming intended interactions, you don't seem to be able to power up characters, the revive button doesn't revive (revive the support at least). There doesn't seem to be an incentive to even fight, you can always escape for free and it is RNG if you do a fight or get free candy, so I was able to save up hundreds of candy and buy out the shop items by just leaving every fight right away and knocking on the door again.
Some of the items in the shop couldn't be bought, the ones I saw were the "Wearable Fangs" and "Bubbles" that had this issue, there was only a few I just hadn't come across. It would be nice if the items functioned as either equipment or consumables, I noticed that the mana potions didn't seem to have an option.
I think it might me more fun if the shop was always accessible from the main screen. There was a shop on the main menu but I couldn't figure out how to go back to it to what I expect is upgrade the characters.
