GoNNER

GoNNER is a 2D side-scrolling platformer with a fantasy theme. It has many roguelike elements with procedurally generated levels, permadeath (mostly), different loadouts that can be chosen or customized for a single run, and items that can be unlocked or are discovered and that remain available for all future runs with passive or active effects. It provides no instructions at all about controls or game mechanics, leaving everything for the player to discover. The game favours a fast and aggressive playstyle as currencies and scores are only provided by building up a combo and killing enemies quickly in succession.

The player's character is a small blob called Ikk. The loadout is defined through three types of items: a head, a weapon and equipment. A head determines Ikk's size and the amount of health, weapons include machine-gun like shots, a shotgun, a laser etc. and the equipment provides an ability with a cooldown period such a series of shots or a protective bomb circle surrounding Ikk. This loadout can be chosen by visiting Death in a level before starting the real game. Levels consist of multiple areas with a large, snake-like creature providing the entrance and exit. Not all enemies need to be defeated to progress. A series of levels is completed by defeating a boss. Between levels there are sometimes small story sections, for instance when Ikk gets to visit a large whale called Sally, who replenishes his health and increases the ammo capacity.

Ikk can move around, double jump and wall jump. Next to shooting enemies they can be damaged by jumping on top of them. When hit Ikk loses health and his head, weapon and equipment are scattered around. If Ikk is hit again before he can retrieve his head, the game is over right away. The player needs to steer him to collect the three parts to continue. Also, there is not an unlimited amount of ammo. Reloading is done by picking up an bullet casing item left behind by defeated enemies, which means there are situations where Ikk is briefly without ammo and cannot shoot. Other element are chests with hearts and purple runes. The latter are left behind by enemies and are used to buy a continue or to acquire new items from a shop in some levels. Not everything in a level is visible right away: most parts are shrouded in darkness until Ikk is close enough.

Next to the main game there is a daily challenge identical for all players with a single chance to achieve a high score and compete on leaderboards against players worldwide.
