I have finished my first NES homebrew game, the side scrolling platformer, Rollie.
However, it is not quite available yet. Like most NES releases nowadays, there will be a kickstarter for it, which will begin in 2 weeks on July 31st. (It is delayed to mid-August now) I still have to do a bunch of promotional work and finalizing deals with people-- basically stuff that doesn't really involve work on the actual game but needs to be done. I'll post the links and what not when that begins.
This youtube video shows some of the gameplay and is something of a trailer:
The strong point of this game is its gameplay, physics, controls, and wide range of abilities for the player to use in order to get past obstacles. The game's most significant mechanic is that the player can roll into a ball and bounce around everywhere. The scale in terms of length and depth is about that of Super Mario Bros 1. The idea was to get a smaller scale game, perfect coding and data practices done before working on a larger game using the same source code, which I hope to do someday after this release is final.
The game also has its own website, http://rolliegame.com which I plan on posting updates, content, and other things related to the game.
This GIF image shows some gameplay from the title screen, which includes a two player mode where the players switch between each other.
