Thanks so much! I'm glad you liked it. You are right, reaching this level of polish was probably the most challenging part. The sandbox/random events idea would be incredibly cool. The main problem I see is that the game currently functions as a resource management strategy game, requiring you to optimise resource consumption (energy) before time expires. At the highest difficulty level, it is pretty challenging because you have to reduce warp "jumps" as much as possible and plan the starbases' docking carefully. Without a time limit, the game would change; it could probably become a tactical/turn-based strategy game with more complex combat mechanics. Very interesting idea to explore.
