whoa this is neat! i really like how you used the exit from dialogue hack as part of how you interact with the planet! it took me a moment to realize to "use" items on things i've already seen dialogue for but thats part of the "puzzle"! i feel like a hint or something could be made for that though? like a invisible item triggering dialogue as you step away after u dig up a item that says something like "the [item] twitches a little" and maybe make another dialogue that says something "it twitches more" as you get closer to a sprite that it interacts with?? but that also might be over kill idk it just might ease that moment where i was like "well what do i do now? i grabbed all the items and talked to everything and there's no more rooms i can go to" not all people give their games endings which is why someone (like me) might for a moment think "oh no is this it?" but i realized you wouldnt have been shown a place where to put the items u find it you couldnt return to the spacecraft
the ending was great and kinda mystifying-i really enjoyed this game! :D
