This game is pretty fun! Needs some tweaks though
I understand that the Autofire option was something that was needed for the game to be more fun, but unfortunately made the game very easy...
I passed the Hell campaign with just 6 Demons in Autofire basically... I upgraded them every now and then, sometimes one would die in battle and I would change the position of another one that was firing to nothing and put him there... and that was it.
The Heaven campaign was harder because of the challenges... if it wasn't for the challenges, it would have been just as easy, except with Angels =P
So, in conclusion, the Hell campaign should have challenges too (different ones) and you should tweak the Autofire so that it doesn't make the game so easy to beat... maybe only a maximum of 3 or 2 guys could use Autofire simultaneously, or you would need a certain number of keys to put more guys using Autofire... something around those lines.
That reminds me, the Girl Angel should be able to Autofire the magic of curing multiple friends, not just the magic of curing one. Same for other guys who can do more than 1 attack/magic.
Anyway, great game! I hope you make more like these, it's a great type/style game that isn't very common but is incredibly fun! =D
I voted a 5 and review it a 8/10!
