Thank you so much man! I was actually just getting on to comment on the last few demos I played and yours was of them as well (I'll leave my detailed comments on your submission page, but in short, it was freaking amazing).
Yeah I actually ended up using a sprite hud even though it might look like a tile hud. The labels are tiles but everything else is a sprite.
And unfortunately I had to change the continue screen right before I submitted the game so that it just reset the game regardless of your choice. It was supposed to send you back to the last checkpoint when you hop into the "yes" portal but I couldn't figure out a way to "untrigger" the screens that contained the time machine parts so I just changed both portals so they reset the game :( I plan on fixing that this week.
