The game plays good, but I have few issues.
1. you can get into infinite loop, where you get 2 shields, get hit for 2 damage and same for your opponent
2. items in shop werent free, resulting in uphill unwinneble battle
3. you have to spent 1 play, after you exit shop, even if you didnt make changes to the loop
other that that game plays well, its fun and unique and has quite a charm, good job. :)
