Well, the mana regen is related to the number of mana boosts you did, so, don't upgrade max mana, cuz if you upgrade it, your number of needed mana boosts to reach 9999 mana is lower.
Very good game.
The strategy for beating 'The End' is to before destroying the enemy castle, max out mana and build as much angels you can, BEFORE DESTROYING. After you destroy it and the big one comes, don't stop summoning Hobbits and Warrior Elves, summon Blue Dragons when you're able to
Very good game
Tricky maps and long-length
It's that kind of game that you can't beat with 1 gameplay. You have to keep it saved and return to do the other maps. About 10 gameplays per person
:D
5/5
2 Reasons I didn't like it:
-The lag
-And the game becomes repetitive after a while,
My suggestion would be to add more bosses, because killing the same bots becomes boring.
I loved the weapon level upgrading, but it should change more things than the color, only the last one becomes really explosive.
Oh, and another badge should be added, an Impossible one, that the achievement would be to lose a life.
:D
4/5
