Big thanks for giving it another go and the awesome feedback :-)
I’m working on a harder “Nightmare” mode that randomly picks 10-20 sec waves from a pool that gets more difficult. It’s going to be 3 mins of hell for the ultimate challenge. My plan is to have it as a single stage but you choose the background and boss you’d like to face.
The gauntlet mode has long chunks picked at random from a pool so I can't really do a level select with it. However, I'll make a big note for the next game to have a level select from the start :-) I love that idea.
I also have some unused tracks I’d like to add with new backgrounds. 1.1 will be the vertical mode with horizontal following in 1.2.
Thanks again, you're a star!
