Best way to make money is wait till mid game so you get a good chunk of population per night, then feed Chester. He usually lends a nice amount of gold.
The real deal is, some people make the mistake of developing "ok" games trying to earn some money by forcing the players to buy something, be it energy or items, since you're not gonna able to advance any further due to limitations on F2P, happens most in CCG, given the advantage of the premium cards. This however is not very effective due to the low amount of players willing to waste money on a browser game, thus leading the frustated players to quit the game . A F2P friendly ( and awesome game ) like this, can hold many more players, and even make them consider wasting some money, and even better, having new players can make the game famous enough for, who knows, even selling the game.
Inglor's piledriver is really annoying, he spams it a lot and it does fairly high damage. However if you use Amano's (fav character :P) unblockable while Inglor is rushing at you, you will pass through him and get to his back.
Having trouble in the last boss? Focus on upgrading the charge. When fully upgraded you take no damage when charging. So, wait for the boss to get near you ( Most likely in your front ) and use the Special Attack to knock him down, Then keep him dazed with continuous Attacks ( but not too fast ) until he dies.
Its a really nice game if you're looking for a quick fun, you got my 5/5. However one thing that i didn't liked about it is the reloading. It is possible to "combo" by shooting ( 6 to 7 times ) while jumping and reload. With that you can easily slay hundreds of monsters, and farm experience + money. Just make the reloading a bit slower, and also another thing add health packs to the store, some times they're pretty usefull!
@uruguay noma, actually halftime doesn't replenish nor spares energy. When the timer reaches 45 mins the time line shows the halftime message, but the game doesn't really stop, causing the impression of sparing energy even when on Halftime.
This game is great, an easy 5/5 for me, nice gameplay, sounds, and such. The artwork is smooth and nice, but the game lacks more weapons, such as bazookas or something like that..You can easily beat the game with two weapons, a Wincherster and a Mossberg. Invest your first skill points in Businessman and Quick learner, and get they to reach level 3. Once they are upgraded focus on improving Fast reaload, you can leave it at level two or max it. You can decide what you're going to improve now.
Little advice: When the player dies, he keeps the money. Make the money that the player collected in the stage reset, because you can easily farm gold coins this way, and buy the best things even faster.
