On stage builder, can you make walls?!?! and a ceiling?? So it would be possible to make a room where you couldnt die, but just get more and more percentage.
You can but you MUST have an entrance or else you just spawn on top of the box.
Also can you skip the SSE cutscenes?
yes you can.
How is the gameplay? Is it much like SSBM? Are there any attacks that just seem cheap or way too powerful?
The gameplay is just like ssbm but you can grab items in the air, and Dedede's side+a is super powerful
And is koopa really as good as everyone says he is?
he has improved alot but i think some people are exagerating but trust me he is better than in melee i can't really explain it that good.
