I continued working on it for a few years. but for some reasons I decided to put it aside temporarily.This is a demo of Act 1.This is a rogue-like shooting game, in which the stage collapses from the bottom. Get through the falling world and don't be crushed by it!Some tips on controlling:- Move against wall while on air to fall slowly.
