Had fun snowballing :)
* The platforming could be frustrating. Implementing one-way collision would be a huge boost
* The platforming double jump power got to be a lot of fun towards the end, being able to ricochet across the map super fast
* Too many wizards kept spawning... my map was filled with them by the end
* I liked (what felt like) high level wizard easter eggs
I think a huge improvement would be to allow the snowball to get faster and faster. Spawning higher level creatures the higher you are, making level 1's slightly easier to catch, things like that.
