Teeworlds is a lightweight online multiplayer game. A visually similar alternative can differ in match pacing, server availability, controls, and moderation.
Invite the same friends to a one-hour session in both games. Record installation time, server discovery, latency, reconnect behavior, controller or keyboard comfort, match variety, and whether a private server is straightforward to run. Include accessibility and community moderation if the group will play publicly. Save the settings that matter so a second session can start quickly.
The official Teeworlds site identifies the online multiplayer focus. The meaningful question is whether your group enjoys and can reliably join the matches, not how many modes a store page lists.
