Meet Loupe, and Take Afterimage for a Spin
Sometimes you want to stop a game at exactly the interesting moment and find out what is happening. Loupe is built for that: open the inspector with F1, look at the live state, and try a change while the game is still running. It works with LÖVE games written in Lua.
If you would rather start by playing, Afterimage: The Glass Reach is on itch.io. Dodge lasers, collect salvage, and upgrade a small ship through three sectors or an Endless run. It is free, and the source is available for anyone curious about how it works.
Afterimage is a playable showcase for Loupe. Play a round, then visit the repository to explore the tools behind it.
