ight so I just spent a bunch of time fixing the following (found by a bunch of people in the NSMB discord):
- Mario used to be able to shoot iceballs in unintended places (i.e. entering a pipe)
- Iceballs, when destroyed at the goal would count as an enemy, which allowed for alot of points/1-UPs
- Iceballs are kinda broken on slopes - however on the seesaw platform were incredibly broken; they now just disappear when colliding with the seesaw.

and a new feature - which allows for koopas to be frozen in a different iceblock depending on their state (whether in shell or not)

the code repository has been updated as well
