KarmaZoo Review (uɹoɔdoԀ)
This was a great vibe of a game, I wish I found the time to play more of when it released and it had an active player base. The whole point of the game is coop with strangers, but everyone that played has gotten their fix and moved on to other games. Less people play, so it takes longer for a lobby to fill up. Players have to wait to long, so they give up and go play something else. Now there's even less players. This game was always going to be a short lived thing.
I would give it a positive review if the developers would figure out an approach to expand to a new wave of players and to give the player base a reason to return at specific times in the year. Maybe free weekends, followed by new content then a holiday themed event. Halloween into Christmas period.
For now, unless you got friends to play with, you gotta just check when the game has it peak daily and weekly traffic on SteamDB and try playing at those times.
