Apologies for the stupid storyline, and for the stereotypicalness (is that a word?) of this. It is possible to get rid of the spikes. Press the flag twice! :)
Cooltext.com for the words on the thumbnail, @vivmsquash for the code on the overall movement of the character, the ability to wall jump, making the character respawn when they touch red, and the effects of the water. Credit also goes to @joshiesays for his project on how to make a thumbnail: https://scratch.mit.edu/projects/100598132/
