This is a homebrew port of Cave Story based on the CSE2 decompilation project, which itself is a decompilation of the freeware version of Cave Story.

Note: CSE2 is one of the open source reproduction of the Cave Story engine, except it is designed for accuracy and faithfulness to the original. Sadly, it was subject to a DMCA takedown.

User guide

Gameplay

The fast-paced gameplay of Cave Story revolves around Quote, a robot who wakes up suffering amnesia and who must explore and blast his way through cavernous areas in order to figure out his backstory and escape from the cave.

The character gains access to new areas as he powers up his weapons by collecting triangular experience crystals and solves various platforming puzzles.

Quote speaks to non-player characters scattered around the game world in order to learn more about the world and its inhabitants.
