Excellent mini roguelike. Made it to lv 30. :) 
And no bugs so far. ;) Can you have sword & shield at the same time? I'd love to see future updates, with a real ending/goal and a purpose for the gems maybe.
Thanks for the great feedback!
Yeah, if you're able to collect them both, you certainly can have sword and shield at the same time.
I had lots of ideas for the game... but due to the memory limitations of the competition I wasn't able to add them all. Like adding a town with a shop for the gems, the ability to go both up and down in the caves, various enemy types and bosses to hunt down etc...
Perhaps if there is enough interest, I'll keep the project going!
I would leave the game as it is (it's great!) and put all the new things into a sequel. I know, roguelikes are a great bucket to be filled with strange ideas. I did a little one (long ago) where the battle system was a game of dice, the lands were littered with casinos and you could find fungi to poison yourself, so you became aware of hidden objects in the map. Fun times. ;)
