More feedback:
+ When going to the menu to load a save, the 3 slots don't tell if there is data or what level/progress/activity I'm currently at. It gives a sense that they might be blank until I click on them, which feels a bit off. I'd like them to say if that save slot is occupied and say some minor data like what level I'm at, how many blocks I've broken and what is my total playtime on that save. Maybe even give player the option to name the save slot during a new game start so that it appears with a label in the load menu.
+ Since the game is long term adventure that can last for days, I think the menu menu would work better if the top option of the list was "Continue" to quickly load the latest saved game, instead of having to remember to click on the Load game page and then select the right one. currently it feels like I could one day click on Start Game by accident and end up losing my save file.
+ When ESC is pressed, I'm not sure if the game world is paused as the player (are monsters, events and such still happening in the background, etc), so it would give me a sense of peace and safety if the ESC menu during gameplay would say somewhere "Game is Paused".
+ There was a tall towering vine with blocks around it. I parked my spaceship at its root and used my jetpack to go up to it, but then got a message that I needed a skull key to open it (later I noticed I already had two of them in my intentory so that confused me why I didn't automatically open them), but when I started to back down my character suddenly started tumbling down in the air, free falling without me able to use my jetpack to slow my descent. I didn't like this loss of control and it felt way too punishing and arbitrary for that to happen. I took heavy damage on impact with the ground which felt unfair since I though I was prepared and had plenty energy for my jetpack.
