I'm loving this! It has surprisingly complete 'feel', the movement of run-gun-bot and weapons. It is a rewarding game that makes you feel some mastery over it, I think mostly in part of the forgiveness of invincibility as opposed to a more retro style insta-death on being hit. I've not completed the game yet, but it has served as a pleasurable way to spend some time. I look forward to following your game dev journey! :D
