I bought Gigapocalypse not knowing much about it because it was super cheap on sale and I liked the pixelated artwork. Game is actually lot of fun, it reminds me of PS1 game Rampage where you pick your giant monster (also known as kaiju), and go around destroying town. You get score points from destroying buildings and enemies, which you later use to "evolve" your monster at the end of each round. Artwork and idea that you only use two buttons for the attack gives it feeling of arcade game (your kaiju moves on it's own like in sidescroller) and you don't have to worry too much about which skills to upgrade as your upgrade points are tied to your score points not skill points, so if you just play game long enough you can eventually get all the upgrades. First couple of runs you will fail because you will get overwhelmed, but after few upgrades, you will easily be able to beat the stages in just couple of minutes, so this game is perfect if you just want to play something for couple of minutes then move on to something else, and there are around maybe 10 kaiju to pick, each playing differently (while using same core mechanics), so there's enough variaty to keep you entertain.
