A very easy, repetitive short game. It took me a little over 2 hours to finish the game, in which I never lost a battle or hp. There are very few bosses in the game with unique mechanics, which barely changed my strategy if at all. There are multiple areas you progress through, each one deleting your inventory of cards and deck upgrades, changing it back to default. The only thing kept between areas is your researched cards, which aren't even needed and many are not very useful. There is a "story" but its just text in between swapping areas. The game is infinitely replayabl but it gets boring pretty quickly.

If you want a quick, cheap game where you don't have to use much of your brain, you could try this out.

Great setup and potential that is marred by stalemates leading to 'dead man walking' runs and bugs.

For $5 I got a pretty strait forward Strategy game that lasted me 7.5 hours. I call that a good trade.
