I am making a 'space' shooter, but instead of space you are in a little bottlecap in a dirty sink. Thinking it will be a wave shooter? IDK. Still working on controls and movement. But as for the theme, depending on what companion you take with you, your missiles will behave differently. some will be slow but powerful, some will be fast and weak. one will act like a land mine, etc. so, you are incentivized to try all the different companions . Thinking of 3 waves, with 30-40 enemy's to a wave. After you beat the waves (different themed levels) you can try to escape down the drain and the sewage pipe to freedom. Will be a short game, but hopefully not TOO easy or too hard.
