On the description page it says
- Shift Key: Press the shift key to reverse gravity. This allows the character to ascend instead of descend. Use it strategically to navigate challenging areas and reach new heights.
However when I press Shift key on my keyboard, I get a tiny jump instead of reversed gravity 🐞
Update: I found that I can fly up indefinitely by mashing keys space+shift. Weird (weird). Overall a fun little game; discovering this bug-o-feature was the most fun part in it
