Played it again and I found a couple problems or things I just generally didn't enjoy.
-The bottom step outside the powerup emporium is too high to walk up, and you actually have to jump. This isn't really a real problem but it ticks me off for some reason >_<
-The sewers that you enter from the emporium are very, very boring. I mean, the gameplay is fine, it's an environmental level, but it actually needs an interesting environment for that, and the sewers are almost completely just the same monotonous brick and black background. Some other backgrounds and different tiles here and there would really fix that up. The only place where I found the gameplay to actually be annoying is that climbing bit near the beginning of the sewers, where you just have to jump back and forth and back and forth to get up the tunnel, and missing by a pixel will send you falling back down again.
-Going through the aforementioned jumping bit a second time.
-Jumping through
this room can be frustrating due to the ceiling being right above the floor where you're supposed to land. There's also a way to die one block after the screen change, which is hard to avoid if you don't see it coming (which no one would the first time).
-Falling down into
this room. When you're in the room above, you're moving quickly to the right and you can't see that hole coming because the waterfall is covering it. Still moving to the right, you fall straight into the water and die.
-When going from left to right between
these rooms, if you jump right before the screen changes you can get inside the walls (though this was handy for getting up to the Lower City without walking all the way back
). I'm not sure how this is possible since the tiles match up; I think you might have put the mossy stuff hanging from the ceiling on layer 3.
-The gameplay up at the top of the buildings in the Lower City felt very limiting. It could have made some great platforming but instead you just walk while holding the down arrow.
And so concludes my list of things that I didn't like about it. Keep in mind I'm completely new to this (joined the forum last night) and I'm not a very good player, so I don't think my opinion counts for much
Oh, also, is there anything in the labyrinth house? I walked around for a bit and hit a dead end in there.
