this is a good start to a promising game! I tried several times to find the rabbit costume, but only the ghost one seemed available. The costume change worked well, as did its special ability! The controls were responsive and accurate!
When you are in the costume box menu, there are 2 buttons. one on the left, one on the right. When pressed, they switch between different costumes! The firefighter has no use yet, but the other 2 do!
The little blocks on the left and the right side of the screen are the ones you need. those are the buttons. i know they arent the best sprite, but i didnt have time to change them :)
