Teeworlds

Teeworlds is a multiplayer shooter game in which you are a cute character with a smiling face and your job is to destroy the members of the other team.

The game can be played online or on the same LAN. If you play online, there are multiple servers to choose from. A server will allow a restricted number of players; so when this number is reached, it no longer accepts new players. The player can select the desired server. Every level, according to the mode selected, has a specific mission to achieve, such as reaching a specific place, plant a flag, protect something, among other things.
You will be equipped with weapons and you can collect more as you play, but you will also need to collect ammo to be able to use these weapons. You have a given number of lives, but you can win more as you play. The player can customize almost everything in the game, including controls, avatars, etc. The game offers simple but nice graphics, nice sounds, and suitable but a bit annoying music.
To conclude, if you are looking for an enjoyable game to play with or against other players online, Teeworlds may be a nice choice.
