This game, as far as any smaller developer games go, feels like a AAA game. It has almost all the bads, and all the goods associated with that claim as well.
Loot-boxes are a dollar to open.
It's filled with promotional stuff.
It's got no official single-player.
server and rubber-banding issues.
Yet, for all the flaws, it has some amazing features.
The graphics are great and run great even on low end systems.
The mode/mechanics is unique and fun.
Multiple game-modes.
steam workshop support.
Competitive and casual game-play are both a focus.
Low skill floor, high skill ceiling.
Cool looking cosmetics.
Local split-screen multiplayer (a rarity these days).
This game is easy to pick up, but really hard to master. There is a beauty in its simplicity, both in graphics and mechanics, yet there are no other games like it except for the game it was originally based off of. It takes the same idea of portal, where you have one really cool mechanic, and you do it, and you do it really fricken well.
Over all, Worth the buy, even not on sale. Just don't pay for stupid lootboxes/keys.
