I tried out your game today and honestly... I'm surprised this isn't getting more love and attention. I had a blast and thought this was very well done! Here's my feedback...
FEEDBACK:
1. I think you should REALLY push co-op/playing with a friend. I don't know if you intend for this to be co-op, but my friend was over, and I was like... I'll take WASD, and you take Arrow Keys. We had a LOT of fun playing this together! Fighting over cards, talking during combat... have you considered adding co-op? Online, couch, etc.
2. I know controller support is coming and the keyboard is great. However, the ability to proceed through chat with space bar or another button on keyboard would be nice. You use WASD and arrow keys to control your ships, so when dialogue pops up, it would be nice to just keep my hand on the keyboard. Not a huge deal, though.
3. I'm not a fan of how cards auto-pop on-screen mid-combat when you acquire them. It would be nice if we chose when this happens—end of level. I press a button. I know we assign the cards once we get them... but it really took away from combat during certain moments. Maybe newly acquired cards sit in a pool, and then I assign them at another point in time?
THE GOOD:
1. Great opening tutorial. Ability to skip for repeat players would be nice (not sure if you can).
2. Love the music. Very fitting for the game. Just the right energy and it doesn't get repetitive.
3. Combat is the best part. I love how we need to watch both sides of the screen, and controlling both ships made me think. It takes some getting used to, but it adds a nice challenge and level of difficulty. Really fun!
4. Love how you get to choose the next level after you beat one!
5. Playing with a friend, sharing the same keyboard, was a LOT of fun :-)
6. Obtaining cards and assigning them to your two ships adds some nice variety. Loved this.
Overall-loved this. Top marks! Keep up the great work!
