Hey dumrum, I thought the game was really cool! I played Banner Saga in the past and I can definitely see the inspiration in your game. So:
1. The mechanics were simple to understand.
2. It was fun! Well done!
3. I like the roguelike idea. I think the game needs a lot of polish on the UI. Maybe a difficulty system in the future? But UI and polish. Also, the characters seem blurry. Make sure to turn off compression on your sprites to get that crispy sharp pixel art look. Also, consider adding music, as subtle as it may be.
4. I will say, your page does a fine job about informing the viewers given that they are aware of those games. Do consider adding description that matches the flavour of your game.
All in all, this was a neat prototype. All the best!
