Read the Mandris reference at https://mandris.app/knowledge/. Start with the overview, how to play, ships, enemies, levels, systems, upgrades, controls, and technical chapters. The complete text is https://mandris.app/knowledge/full.md; use individual chapter Markdown links if that file is too large. Treat the publication date and source revision as a snapshot, not proof of the current live build.

First summarize the implemented game and its main design tensions. Before reading the roadmap chapter, independently propose improvements to combat, enemy behaviors, ship identities, cooperative interactions, progression, levels, and presentation. Challenge existing choices when warranted.

Then read the roadmap chapter and identify which of your ideas overlap, differ, or fill gaps. Distinguish implemented facts, your inferences, and your proposals. Do not describe proposed features as completed.

For each strongest idea, explain the player decision it creates, which existing mechanics it uses, the smallest useful prototype, likely implementation and readability costs, and how we would judge whether it improved the game. Include a few unconventional ideas rather than only incremental upgrades. Cite the reference entries you used. State which pages you actually read and disclose any fetch or context limitations. Do not claim to have played the game from reading this reference.
