The most important reason for this update was that the Linux version is no longer working out-of-the box in many of the modern distributions due to removal of required old libpng library version. Also, a lot of bug fixes and improvements have been made to my "engine code" over the years while developing Hyper Ultra Astronautics.

Taking cover behind shield

I decided to drop the built-in level sharing mechanism, because it was a maintenance nightmare and due to the fact that during last three years it has been used only three times in total.

I will no longer build a 32-bit Linux version, because practically no-one downloads that anymore.

Here's the full list of changes:

  • Dropped Direct3D support (was never used by default anyway).
  • Fixed some compatibility issues on Linux (no more libpng dependency).
  • Added monitor selection in system menu.
  • Added monitor gamma adjustment in system menu.
  • Added V-sync interval setting to system menu.
  • Prevented "Automatic lockdown.." voice announcement from playing in editor preview mode.
  • Rewrote collision sound volume calculation.
  • Fixed random crashes at exit.
  • Added itch.io manifest files and cleaned up remaining references to Desura.
  • Switched to use SDL2 game controller mappings for much better gamepad support.
  • Fixed crash when starting level editor repeatedly.
  • Removed level upload/download support.

There has been a lot of code changes, so I would be surprised if there are no new bugs. If you encounter any problems, please report them and I'll sort them out.

The free playable demo version which lets you play first eight single player levels and one multiplayer level. Besides locking rest of the built-in levels it's otherwise fully functional.

Why can't I play any of the levels I make?

I'm sorry I missed your comment here (I'm still not getting any notifications on new comments here).

Is the created level missing from the list of levels to select, or does it give some error when you try to play it?

The level must have a single player start point for it to be available for single player games.

When I load a level I made, the screen just shows the background and nothing else happens. I put in one of those SP Start blocks but it's like none of the objects load.

Problem solved, I replied to your email.

The game expects all moving stuff like enemies to stay inside area formed by wall/floor/ceiling blocks. The level in question had a lot of enemies placed outside outer walls, which eventually caused problems when starting the level.

Any plans on local coop game mode? Also known as 'couch coop'

Sorry for the late answer. There are no plans for a coop mode, local or otherwise. I have thought of local split screen multiplayer mode for basic deathmatch, but I'm not sure if that will ever get implemented.

On console I get this msg " /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.14' not found (required by /home/rodrigo/.desura/games/14729/3496/lib/libXaw.so.7) ". The libc6 is out of date?

My system is Debian Wheezy 64-bit and I run apt-get upgrade daily.

The game is known to work in Debian Squeeze so it should work in Wheezy too, since Wheezy likely has later version of libc, which is generally backwards compatible.

That libXaw.so.7 requiring GLIBC_2.14 is installed by Desura, so I don't know where it came from. I will have to look into this. I will let you know when I know more.

In the meantime, if you have the time, you could try the direct download version. That might work better, since it uses libXaw provided by the system.

Great! Your reply was very helpful. This commands solve the problem for me:

cd .desura/games/the-platform-shooter/lib (I'm using the Desurium client)
ln -s /usr/lib/x86_64-linux-gnu/libXaw.so.7 libXaw.so.7

Thx!
