Just beat it if that helps. This is once again asking the player to one tile jumps, having no forgiveness via powerups or otherwise to allow the user to even make a single mistake. Like for example, I have no idea what the purpose of the giant goomba that's bouncing around, but for me, it just makes the jump harder. Also, what were intending with the green shell & pipe with the firey piranha in that same section. Killed myself enough times trying to mess around that I skipped that. If I was on the upper-side of the map, there was at least one blind spot into a huge gap. While I didn't run into the sideways springs, I feel like they're almost just an extra annoyance/being mean as opposed to challenging anyone.
For example, I'd at least take out the last fire piranha in the stack of Koopa Troopas at the end. But hey it's day 1/2, so I'm expecting folks to get a bunch better as time goes on
, especially since you're asking for feedback and trying to improve. Sorry if the commentary was a bit harsh though.
