I thought the combat was a bit slow. I would have liked a version of it without the text after I understood how to do it. 

I wish after selecting one gem, I would be able to hit B to unselect it.

Great art style. And I liked the turn based strategy and the general vibe of what the texts say. I don't think it needs an overworld.

Maybe increase the damage-to-healing ratio so the battles don't go on so long. And add some sort of tutorial so that your game teaches people instead of the description

Really fun game :) I didn't read the description so I had to figure out the mechanics myself, which was quite interesting. Despite this I reached the end on the first try. I like the simplistic style of the game and had fun with it!

I really like the combat system! It's nice to combine the gems to a spell that fits the current situation.

I didn't like that the special spells that you can cast consume all gems and not just the required gems. 

I like cats and had two of them.

Also some bugs or weird things I noticed.

- I didn't had music until I disabled and enabled it.

- Sometimes the blinking animation that happens, when an enemy has low health made it seem like they are already dead. I think that happend when a texbox appears in the wrong moment.

- It felt like some enemies didn't do anything during their turn.

I really like what you've made. The pixel art is awesome and my favourite thing is the way that the gem system works and how you can improve the stats. My least favourite thing is the way that the character moves between places as it is text based. It still works fine though. But I think an overworld would be nicer. I had a cat once but had to give him to someone else due to an allergy
