I don't normally write about fan-made Metroid games (those that use sprites from the Metroid releases on the GBA), but this Construct project seems different enough to warrant a mention here on IndieGames.

Minitroid is a 2D platform game that is currently being developed by Metroid fan Tokinsom, and a short video that showcases the sprites in motion was uploaded to the internet sometime last week. Being a fan work, it should be safe to expect that Minitroid will be released as a free download for Windows when it is completed, although no release date has been attached to the project at the time of writing.
