Hexoshi - inspired by Metroid

Hexoshi (forum thread) is a libre game generally inspired by the Metroid series, notably the older versions.

It is seeking funding using CrowdSupply for a budget of at least $1100 to achieve "Milestone 1" which involves fleshing out the first world of the game, including new enemies, player abilities, and 30-40 rooms, and the graphics for it all (which seems to be the bulk of the funding requirement).
