Fun ... but there are a few problems. 1. No skill is required to win battles: battle tactics are obvious, and unit composition virtually determines the outcome of battles anyway. Worse, the right unit composition can be acquired by repeatedly reshuffling the Mercenaries available for next to no cost. 2. Some of the units do absolute jack. Slow-as-sin Mammoths and the bombers that never seem to shoot are the main culprits. 3. On a single play-through, the player won't experience most of the units.
AAAAAAARRRRRGGGGGGGHHHHHHHHHH!!!!!!!! I just spent ages getting through the game with only killing 11 enemies because I thought the award was for 20 enemies or fewer!!! ANNOYING!!! :D
The game suffers from serious balancing issues. The Temple is next to useless, because it gains exp so slowly, and does so little damage given its pitiful range. The Crypt gains exp too quickly -- even if you don't upgrade one, it can still easily rack up 4000+ exp by the end of a game; its three shots extra shots, range, high damage and the fact that it doesn't shoot so slowly means that early on it takes all the kills and so upgrades so far that other towers become pointless.
Problems: 1. The game requires FAR too much grinding: no one wants to have to repeatedly attempt to complete the same level for exp/coins. Secondly ... no one wants to have to do that 4 times, once for each of the characters. 2. Wisdom is a pointless stat; agility less so. Strength is by far the most useful stat. 3. As far as I can see, there's no benefit to getting a large amount of chains in a row, as opposed to getting lots of very small sets of chains, which seems rather pointless. Secondly, no one is ever going to get a million chains. Seriously. 4. The special ability is over-powered. Make Wisdom more potent, and make the ability less powerful. 5. Make it easier to go up levels; have a thing to say how much exp you have to go until the next level.
I just realised -- if I hadn't got bored at the end and started shooting people in the feet, I could have got 500 headshots instead of 496. AAARGH. Good game -- the barrett is insane, though.
Bog-standard shooter. The fact that you can repeatedly play levels until you have all the upgrades makes the whole game a bit silly -- at no point do you have to use a modicum of skill, only grind away at levels until you have enough cash to purchase billions of upgrades. It's pretty, though, and fairly satisfying. 4/5
Massive, massive bug, and I haven't a clue how I triggered it: on day 4, I'd messed up, so I hovered my mouse over 'Options' and (I think I might have clicked "Show Cutscenes")... then I got the ending video and it told me I'd completed the game in 4 days. What?!
