I have now played after the developer has updated the game, the main changes were to fixing the UI visibility (which was quite nice) and reducing the damage dealt by the turrets. Overall, I like these changes, but which there was a bit more tuning done. Level 2 is now much more enjoyable, I think most of what I said about can be disregarded. Level 3 is still somewhat painful, and I can't tell if it was easier because I had already done it once before, or because of the balance changes. Still I think these improvements are nice, I appreciate the dev(s)'s ability to take criticism and improve their game with it.
