First of all, thank you for providing support for DualShock-style controllers (like the ones found on the PlayStation or XBox), both standalone and alongside mouse aiming. It saves me the pain of having to risk experiencing carpal tunnel syndrome when using keyboard controls.
Secondly, I'm guessing that a save system not unlike a Metroidvania game, or a survival horror game like Resident Evil or Silent Hill, is planned somewhere in the future, right? Hopefully, it'll be not too distant in the future, especially as the game presumably gets progressively longer and longer as it gets developed further and further, to the point where not everyone would have the time to finish the whole game in a single sitting, right?
Thirdly, with the exception of those that were too far away to reach, I think I managed to melee down every single plant-monster that I had come across without firing a shot. Perhaps that might merit an achievement?
