Inverse Polarity is a short platformer schmup created for GameJolt’s Axiom contest (August 2009).
I don’t feel that it is complete, but I’ve been suggested to post it here because it’s been an enjoyable play for some.

Doesn’t seem to run on Linux. :frowning: I’m not getting any errors to report though, it just never appears.

#3

Can you turn on logging and report it here? I’m not sure howto under linux, but I’m sure somebody knows. :slight_smile:

#4

Turned logging on, and I still get nothing o_O

#5

Seems like a fun game, but the game window is way too small. Also Z is not a good choice for a key binding, since it is in different places for different languages. Maybe use Space to jumo and CTRL to shoot or something.

#6

I’m waiting on a bug in Slick to be fixed so that game window can be set and scaled (resized) properly.
I will add in customizable controls in the next webstart update. I’ll post when it’s published.

Thanks for the feedback,
Ashley Gwinnell

Nice little game which has an overall polished feel.

It will be nice to see how it develops :wink:

#9

Another Linux report. I thought it has failed to load: sound was playing but the applet window was plain black. However, in the few minutes it took me to look through the console output it finally finished loading.

Note: the console includes a lot of messages saying “WARN:class org.newdawn.slick.opengl.PNGImageData failed to read the data”.

#10

Nice concept art!

I’ll try it once I have time.

#11

I believe this one simply means the PC’s video card doesn’t support OpenGL calls.

I know about the warnings, but I’m not sure why it takes more than a minute to load.
Is it pausing and then outputting that warning, then pausing again, loading (for each image), etc?

Heh, that’s pretty good, I like the style of it. The reversing gravity thing (going every 5 seconds) is kind of annoying, though, I’d rather be able to do it manually.

#13

Yeah, that would make it a lot more fun.

#14

just to confirm the game works fine here on linux.

Very nice and polished, however a little on a short side (a bit too short atm), planning to add a few more levels?

#15

Fixed my Linux and now the game works. Sorry about that. Anyway it’s a great game, but it’s too short. If you added more levels I bet it would get featured!

#16

Very nice game! And incredibly polished for a contest!

Like others said, being forced to change gravity is frustrating. Please change that with a key.

Do you intend to add levels?

And the screen size is too small.

#17

Just uploaded a quick video of the work-in-progress menu, which, is functional as a menu, but not functional in terms of what the menu options are (i.e. multiplayer and timeattack both do nothing).

Without further adieu:
