No problem at all; thank you for taking the time to write out thoughtful replies and explanations to everything! I will definitely be downloading future updates and I realise the game is far from finished, so I'm sorry if my feedback come across as too harsh.
Regarding what I said about the cannons and a timer, that was just me misunderstanding how they worked.
I did notice that making many turns while fighting the enemies was the best strategy, and I quite like that.
The features you have planned sound excellent and I'm looking forward to any progress you make!
