Battle1 - 8.5. Despite it being overused, I find Battle1 to be a good level. It has that nice passages feel which is missing from so many platform levels.
ABattle1 (1.23) - 7.5. Some of the edits translate into major flaws.
ABattle1 (1.24) - N/A (I haven't played this one enough)
Battle2 - 7.7. I like this level. However, there are not quite enough routes.
Battle3 - 6.7. This level has practically no layout, flow, design or gameplay. Fortunately, the ammo placement's ok.

Capture1 - N/A (Not sure what Capture1 is)
Capture2 - N/A (Not sure what Capture2 is)
Capture3 - 7.0. It's an ok level, but it's heavily unoriginal, and the design needs some work.
Capture4 - N/A (Not sure what Capture4 is)

Treasure1 - 8.7. This is possibly my favorite Treasure Hunt level. Everything about it is great.
Treasure2 - 7.7. Pretty well done, and the airboards are fun, but there's not enough incentive to stick around.
Treasure3 - 6.7. Way too boring for my tastes.

Race1 - 7.2. I'm not too much of a fan of countdown blocks, and while I'll admit the floatup area is well done, the rest is a bit boring.
Race2 - 5.5. Not much to say about this one.
Race3 - 6.2 It's ok, but nothing very special. I have some nice memories here of not knowing how to run, though.
