Interesting idea, and nice visuals! However, I couldn’t get past the second level - I think the camera is supposed to scroll but it didn’t? I also clipped through the floor. Clicking the “Retry” button also made the spacebar keep triggering the retry button, I’m guessing the button had focus and the spacebar would activate it until I clicked elsewhere on the screen.
It’s a shame since I wanted to see what was to come in later levels - having multiple characters with different sizes and skills seemed like a fun idea for a puzzle game!
