I had this game on my phone, and put around a dozen hours into it and never got close to bored, and wasn't even mad/upset when I had to start over for the PC version
This is the classic Snake game with a twist. Instead of a 'snake' that get's longer when you eat a pellet, you're an adventurer/warrior, and the 'pellets' which drop fair rate are warriors that you collect and 'add' to your party. Your adventurer, and you party both attack the various enemies that run around the levels.
Each warrior is unique in their appearance, stats, and the way they attack sometimes. The Mage is squishy but hurls powerful fireballs. The Knight has a lot of health, damage, and armor, but attacks at a somewhat slow rate. The 'Gizmo' is a little dude with goggles that hurls very
powerful bombs with a large radius at a very
Each warrior can be 'leveled up' 3 times, each level giving new stat increases or sometimes even benefits. The Knights first level increases his attack speed, while his second and third levels increase his armor, which makes him very difficult to kill unless you decide it would be great to punch that 30 foot ogre with your face.
There are about 7 different arenas for you to progress through. You start in a forest, go on to a sewer, etc. When you reach the final area type and beat it, it loops back to the first forest, though the difficulty increases continue. And while I never done it before, I believe beating the final area the second time 'wins' you the game.
Each time you beat a level for the first time(including the second trip levels), you unlock a new character. All characters you unlock can be picked up and added to your party during the game, so your 'length' get's quite long. For example, if you have 5 characters unlocked, your line can only get 5 long, and you continue to battle through the levels. If you only have 2 characters, then the line will only be 2 characters max. There's a total of 16 characters, which equates quite a long line if you can keep them all alive, and each one of them has a unique attack to add to your parties killing machine prowess.
Along with the characters and their 3 levels, there are power-ups that defeated enemies drop, and they do temporary effects like giving your a damage shield, freezing all enemies for 5 seconds, increasing attack speed for 30 seconds, replenishing health, etc. You can upgrade these items multiple times, 10 times I think, and each time increases its potency/length/radius depending on the item.
All in all, this is an amazingly fun game that I believe all should play. If you ever loved the classic Snake game, then this is absolutely a must buy even if you are bored with the original. I got this on a sale where it cost $0.50, but I would happily pay the full $5 for this great game.
