- Found a couple more secrets! And now there are more enemies showing up in some levels, which makes leveling up a fair bit easier. I even hit Level 4 once! One of those secrets I only found by accident, though... (I'd played about 2 hours prior to this.)
- The reload time of the shield-throwing enemies seems too long--sometimes I'm just sitting there, waiting for them to throw again so I can hit them.
- The reverse-gravity particles could use some more contrast--they're a bit hard to see on gray backgrounds.
- Mad props for making the ice platforms catch you at the ends!! Ice physics are much more fun when they're not screwing you over ^^;
