Nice game! Good job, guys!
Personally, I don't like using the spacebar for the ability. It was a little confusing with the jump.
Maybe it would be better to use WASD for movement, Q for Teleport, E for Expand, and Space for Jump.
Thanks for your feedback. I will add a control setting feature when the grading period ends.
By the way, the game was created by only one person, only me. So thank you.
Oh! Sorry for the mistake hehe... My English is not very good...It's a really really good job for only one person.
