Thanks for the bug report! Indeed, I've personally only tested on windows sadly. I'm sorry you can't play.
It sounds like the shaders are not intitialized correctly/at all. I've just built in a quick-fix for the incorrect shader loading.
Have you tried version 0.0.1? What version of OpenGL are you using?
0.0.1 works on both machines (but crashes when I get attacked).
2010 laptop: Intel Corporation Core Processor Integrated Graphics Controller
OpenGL version string: 2.1 Mesa 19.0.8
OpenGL shading language version string: 1.20
OpenGL ES profile version string: OpenGL ES 2.0 Mesa 19.0.8
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 1.0.16
2015 miniPC: Intel Corporation Atom Processor Graphics & Display
OpenGL version string: 3.0 Mesa 18.3.6
OpenGL shading language version string: 1.30
OpenGL ES profile version string: OpenGL ES 3.0 Mesa 18.3.6
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.00
Yup, that indicates to me that the shaders aren't initialized properly. I fixed the problem earlier today, so in the next update you should be able to fully play the game albeit without shaders, sorry :| I'm not a huge OpenGL expert, but I hope at least playing the game is fine for you!
Is there the possibility that you could test it with windows? Because I don't think it's Linux. My guess it's the intel integrated graphics
