Trapz io is a combination of platformer game and multiplayer mode! It's probably the only multiplayer game of this style. If you still remember how to play Mario give this game a try!
How to play
The main goal is similar as for many other io games. Get to the top of the leader board. You receive points for coins collected and for players killed (you get the coins player had). So go climbing up the labyrinth, but be careful with traps, spikes instantly take 50% of your HP. This means if you touch it twice you're dead. Recover HP with hearts.
Combining platformer with a MMO is a kind of difficult task, beacuse platformer always has an end, whereas multiplayer io game can't have multiple tasks for every player. So the gameplay can be boring after a while. But you'll certainly can have fun with friends for 15-20 minutes!
