Hi! Very nice game, gives cosy feeling.
Checked your ideas for futher development and I think you are at right direction with āTime pressureā. On the other hand, restricted moves count would make it challenging too, driving game more into puzzle genre - not action game.
One more thing Iāve noticed is that ship vs ship collision exists but isnāt changing anything right now, doesnāt raise any difficulty at all. Perhaps this could make some interesting mechanic - like changing shipās direction.
