It wasn't that tough, but I liked the concept. I think A_Man53 got a lot of the things I thought down. Good game. I hope to see a second with those improvements.
I love the levels were you have to react quick to save the peasants. Just feels cool making the shot right when you need to and destroying whatever death machine the castle guys set up.
I really like the game, I just hate this wait for health to rebuild, pay to refill stuff. I know I'm not the only one from reading the other comments. I see the point from the money making side of things, but I don't know. I kind of wish there was a free version without these restrictions on healing etc. that maybe had fewer cards or something, so I could still play unhindered and those who want to pay can have the full experience. I don't know. I do like the game and will play for a bit, but I tend to burn out faster on games were I get one or two fights and then have to find something else to do for 2 minutes.
Great addition! I really dig these games. Keep this one going, but I'd like to see another in this same style with some other classes you could choose from and some more customization. I like your skill system a lot. All in all, I love this! Keep it up!
