I think the particular texture you’ve chosen for the hazards could be played with - the top 50% suffers from a “is it or isn’t it there?”because of the fading in and out. Maybe a more persistent texture?
Yeah, definitely get the difficulty is partially timing the fucking - an autofuck setting would be the happy medium between intention and accessibility, since it preserves the timing you’re wanting. It would also make hand-strain issues way less of an issue, since it is literally an issue for the game in its current state.
It genuinely might be artistic difference that leaves me unable to engage with the double jump then, if that description is exactly what you’re trying to convey! I’ll be curious how it feels with less slippery controls - then again, my favourite platformers are precision platformers, which doesn’t feel like your aim here.
Glad you appreciated the comment, hope there was some insight you could glean from this!
