My girlfriend bought me this game today as a surprise gift through Humble store. After checking its Steam store page, I was a bit confused as to what she actually paid for, since the game was listed as free to play. Turns out the game is free with a sliver of content and then you have to pay for the rest.
The game is very colourful and pretty, but also poorly optimized. My (admittedly aging, but still very able) notebook couldn't hold the fps consistently up. I could live with that, if the gameplay wasn't so bad.
The game feels really simple, but not in a good way. The maps in the mission I chose to play were all flat pieces of land with some enemies and several mob-spawning towers. Fighting felt sluggish, imprecise and pointless. I played the game with two bots and would sometimes let them kill the monsters in my stead, because to do it myself was just a painful experience.
During the 33 minutes of gameplay I found two bugs. One was an invisible boss that spawned after I killed the actual boss. The invisible boss was constantly roaring and attacking the ground, probably mad about the game quality and his lack of visibility. The other was a graphical glitch, that showed huge white tile under another boss monster. Neither of these bugs were game-breaking, I managed to finish the three stage mission fine. Then again, they were annoying.
There are only three characters. They have one skill each (there might be more to unlock through coins, but I never got that far). They apparently can do skill combos together, but this just didn't happen for me and the bots. It wasn't badly needed though, as the combat was not enjoyable anyway.
Even though the Evil Genius's sidekick encourages you to "Enjoy the looting", there is no actual loot apart from coins.
You are encouraged to use physics to throw objects and animals (!) around to hit your enemies, but most of the time this just doesn't work. Sheep are for some reason thrown in a big arc, over the heads of enemies you were aiming at. Even with careful positioning, I was not able to hit anyone with sheep. <- This sentence now looks ridiculous.
The developers stated that this game is supposed to be enjoyed as a coop game with three other players, but I don't see how I would persuade anyone to buy this. And now, according to other reviewers, the support of multiplayer has been dropped (I haven't tested it though), so their selling point is... gone.
In short, the game is really simple and doesn't stand up to the competition of Torchlight, Diablo and others.
I understand this is the maker's first game, I've read about all the troubles they had while developing this (one dev even had to sell his car) and I wish them good luck in the future. Still, I can't recommend this game.
