Thank you for trying it out! There is regular jumping and charge jumping, if you hold spacebar and release it within 0.2 second it is regular jump with a set height, but if its more than 0.2 second, the charge meter starts. This means the jump don't occur on the press but the release. That I suppose is the downside of having the two types be tied to a single button. Since that prevents me from making the type of jump where releasing the button makes you fall instantly present in other games for precision movement. Noted, when I make changes I'll rework regular jump and find a different button/way to trigger charge jumping.
