What Little Triangle is
Little Triangle is a 2D side-scrolling platformer built around jumping. You control a small triangle and clear levels using jump and double jump. Each level is designed quite differently from the last, so the layouts keep changing as you go. The game ships with more than 60 triangle skins to unlock and use, plenty of enemy types, a bunch of bosses, and levels packed with small details. Two difficulty levels are available from the start: casual and hardcore. Pick the one that matches how hard you want the run to feel.
Playing together
The same platformer mode works solo or with up to four friends in local co-op, so the group can run levels side by side. Alongside it sits a local mini Battle Royale mode, which keeps the same move and jump controls but adds attacking and hiding. You take opponents down by jumping on their heads or by using the various weapons and the different mechanics each map offers. That mode is built for short, chaotic rounds where everyone is out for themselves. The game also supports Remote Play Together, so people who are not in the same room can join a session.
Before you start
Expect a mix of easy pickup and real challenge. The controls are simple, but levels are built to trip you up, and the hardcore difficulty setting leans into that. The Battle Royale mode rewards learning the maps: weapons and mechanics differ from arena to arena, so knowing what a map gives you matters as much as reflexes. If your group wants to cooperate, go for the platformer mode; if you want everyone fighting each other, switch to Battle Royale. Both are included in the same package.
