Yeah, I am for sure changing the tab method to a menu style to compensate for later mech additions, but with release rather than a separate button. I just wanted to change it for playability really (temporarily).
End room text is different, it should have shown up when you entered the room rather than hit a button.
The bomber key is now space, so I figured there was no reason for a prompt, as players would (hopefully) hit space to jump and discover both that: they can't jump, and jump key shoots a bomb.
Thanks very much for playing and the feedback.
