This was a very solid idea for a game. Had a fun mix of roguelike level ups/upgrades, and action! I think my biggest issue with the game was not knowing what all of the upgrade cards did. There was one, in particular, that I felt was going to give me more ninjas (which it never did). One card I never actually tried because, to me, the icon looked like a walnut and I didn’t understand that they would do. I really feel one of those upgrades should have allowed me more ninjas. Of my three attempts, I never got more than 4 to split between two directions and I constantly got 4 or more enemies from both sides. I may have just not upgraded the right card.
Over all, the gameplay is fun, the graphics look really nice, the game plays well, and the music and sound effects work very well in the game! Excellent work!
Here’s a link to my stream of the game… in case you’re in the mood to revisit that train wreck :D
