Thank you so much for the feedback! I do plan on updating the game in the future, so this is very useful.
I definitely agree with what you said about the keyboard swapping, I like having it but perhaps it should be implemented in a different way. Perhaps a control swapping laser...
I'll also have to look at the movement and collisions and see what I can do, right off the bat I can think of a few tweaks I can make to help.
Thanks for playing, and I'm glad you enjoyed my game!
