Hi Oolcay Hitsay
We played your game on stream at twitch.tv/itsalanpham. The viewers love your game. It's the most polished demo we have ever played. I really enjoy the card combat system and the mana/health system.
The only feedbacks i would give are:
1. Make a more engaging trailer. Maybe skip the first part?
2. More intense music during combat and add SFX to emphasize the attack
Great job! Wishlisted!
