Heya and glad to see you around here . I just saw this on the MoHPC forum and was impressed by the graphics. It's nice to see more HP Prime games using the ICON/DIMGROB features to their full potential.

Aaah ok I see. From what I could see on MoHPC and here so far, though, your English seems pretty understandable in general (more than certain Americans who speak English as native language ). Since many users here are French, German, Polish and Dutch, they usually don't mind grammar errors from those users.

And yeah I started HP PPL programming in March on the HP 39gII, but that calculator was so buggy that I had to reflash it every hour or so. When the HP Prime emulator came out, I started experimenting with what I knew and when Critor ran some of my programs, I was amazed. Even without DIMGROB and BLIT, I still got a Tunnel to run at 60 images per seconds (now 90 FPS after optimizing), then I found the image commands. I just need more time and motivation to finish some of my project ideas.

Anyway, for the game, I just played it and it was quite fun. I managed to finish the first level at least. I wonder if you could add small translucent arrows on each side with the FILLPOLY command so that we know where to place our fingers on the screen to move around? Because I sometimes found myself trying to move, to no avail, due to touching the screen at the wrong location.

That would definitively be great additions!

Also nice avatar, I still need to grab an HP 50g at one point, but they're more expensive than the TI-Nspire CX CAS over here ($207.99), so I'll have to look for some online deals.

By the way, I noticed something at the start of the game: The field is not rendered instantly. It gradually appears on the screen. Do you draw everything directly to G0 or do you use one of the extra GROBs? If you use another GROB than G0 it could reduce risks of flickering (although I haven't encountered any so far) and you could add some effects like transitions between screens (like this screenshot, although the fade-in part can be annoying to implement )

Hello again!
I have several calculators, most of them very old. I collect "home computers" and old calculators, so many of which have become obsolete.

The HP50G is an excellent machine, which these days leave with my son to another city. My son is going to start studying to be an engineer, and HP50G will be of great help.

As GROB, "think" I'm working on G1, I have not yet clear how the graphics system of the HP Prime (there is very little documentation!) Works.

Also notice that I draw the screen from top to bottom (in that order is that the program processes the contents of the array that stores the description of each board)

This is looking awesome so far!
Keep up the great work!

Thanks!!!!

Pretty cool looking.
