Thanks for the feedback!
- I've added ESC pausing in single player to the TODO list. Good call.
- Yeah, the SFX hasn't even had a single real pass over any of it. The guy who was gonna help me with it has been super busy so I just grabbed random stuff off the web and slapped it in there.
- I actually want to change how I do the whole item thing; I want to avoid power-ups mid-run and make the game a series of 3-4 minute sprints with a boss fight at the end, and then in the cool-down period you spend the level-ups. That way I get to keep the items more complicated and randomized but don't have them tearing apart the game flow. That, and they definitely need icons and keywords, but UI still needs a major pass.
Still, I'm glad to hear overall you had fun with it!
