I miss the days when levels got harder as you got further into the game, rather than sadists putting a RIDICULOUSLY hard level right at the beginning. But hey, I'm old fashioned.
I love this game. It is really well done, apart from the constant English language problems with the mages, such as using plurals when they shouldn't, but other than that I have no complaints. Incidentally, I was from the great sea, and i found that once I fully upgraded the mana drain spell, I easily won all battles.
There is almost certainly more skill than luck required for this game. Your choices concerning the highest scoring yet lowest number dice combinations are key to this game. All you need to do is think carefully about which dice to choose, and not just click every opportunity that comes up. Forgive me for stating the obvious but it is quite clear that some people need to think about some basic probability theorems.
If you want the combo bonus, then kill the nanoswarm until it has lots of small things, then stand just outside the entrance. When you fire through the gap with bananarang you get combo bonuses.
It is far too easy to completely obliterate almost any level with the right type of unit. Just check the waves on any level for absorbs and strengths, and pick the right element accordingly.
Last boss was awesome. 8000 health left but only just. When you can fire your arrows at him without hurting your people, do so. then send everything at him when you can, waiting for angels if need be. neverstop sending the first five creatures once you've got the boss
