Thanks for playing! Did you get the stomp upgrade? If you already got it and it's not working, I'll try to fix it.

Oh, got it now. It didn't show the interaction symbol and when I was trying it before I must have been outside the area. I like how minimalistic the game is and how you used all of the special skills in the boss fight but after I finished the boss fight (my character froze so i suppose it was end) the ant went to me and screen went black. Don't know it is intentional this "dark" ending. I also encountered this bug where if I jump right before triggering dialogue, the character flies away :D I think you are keeping the y speed in dialogues or something, check that out.
Edit: I now found your comment that explains the dark ending is in fact a bug.
