I am developing the Shmup Simonnus in the last 14 months. Simonnus has local network multiplayer with Arcade and Space Battle mode for Android (for now). Arcade is the classic mode with many levels up to 3 players in co-op. The Space Battle mode generates endless levels randomly for an unlimited number of players in co-op. The idea is to enable many friends to play the same level in a shmup in co-op. Each friend in your smarthphone or tablet.
Features:
- - Spaceships with different shots and skills
- Arcade mode with 60 levels
- Changes in levels for each time that you play, to create more challenging levels
- Space Battle mode that creates endless levels randomly. The levels created have a factor to show the overall difficulty of enemies (difficulty factor)
- Share of created level in Space Battle mode with your performance, to challenge other players, to beat your points and difficulty factor
- 32 enemies, including bosses
- Several side missions
- Singleplayer and co-op local network multiplayer
- Languages: english, portuguese, french
