- Alpha: At this stage the project is playable as a game and gives a good indication of how the final game will play. There may be large gaps, and indeed every individual system may need significant work, but you should be able to test the entire flow of the game at this stage and have a viable experience despite the gaps.
- Beta: All the gaps are filled in now. Improvements are still possible or needed throughout the game, and some chunks of content may still need finishing, but all the systems should be present and approaching complete. Testing at this stage can hopefully focus on finding out what parts of the game need more improvements than you thought.
For now, enjoy this playback of a solution for one of the new levels.
