I played your levels! I couldn't beat Tricky Course or Beware Lava, though. Perhaps Tricky Course requires some Mario Fu that a filthy casual like me doesn't know, and Beware Lava! didn't appear to have a solution at all; the only path I could find led to an unpassable field of spikes, so maybe you hid the real exit somewhere I couldn't find.

Overall, though, I really liked your levels! They were decently challenging without being stupidly impossible (not that stupidly impossible levels are "bad," I'm just not the audience for them. ^_^) I thought Short N' Easy was a nice little experience, and Companion Koopa was clever (though I felt it could have benefited from a checkpoint.) Overall, they were great, and thanks for sharing them!

That spike field is passable, it just needs a good running start and some air turns.

Yeah I know but Checkpoints weren't in the game when I made companion koopa.. However the flaw with that is then you'd have to run back to the beginning to get the koopa again.

You'd have to include a second Koopa if you wanted a checkpoint, and I could see the problem with that. Though you could potentially have put a pipe with some means that only allows you to open it one way to let the player go back and get the Koopa (you can carry Koopas through pipes, right?)

See, that's the kind of juju I was talking about. I have no idea what an "air turn" is.

Well, after guessing what an air turn is, I went back and finished those other two levels.

I shall download and play. ^^

just had a go on all of them and they're well made, my favourite of the bunch being companion koopa x3

couldnt complete the yoshi enters the castle as i got too frustrated by the spring and those 3 note blocks, since i feel theres always issues with the precision of their bounces in all the 2d mario games xP

and as for the tricky course one, i just couldnt even work out how to get past that first part with those floating blocks and piranha plants so i couldnt really experience the rest of that level x3
