I tested it with two computers, both using Linux and wine. One has openGL 3.3 and the other one has openGL 4.6. The laser and the shooting, as well as the image in the main menu is only visible with the 4.6 version.
I found some bugs and other interesting stuff worth mentioning. I'm adding a video showing them.
- When killing the mini boss is possible that it dies with the fists extended. Also you can climb over it and move around with it.
- After dying you can no longer grab the cubes. The hunger and energy are both empty, but you can keep shooting. Also the tamabuki becomes unusable.
- The second mini boss dies with only one shot. I'm not sure if this is intentional or not, but it was funny to see it.
Other than that, it's growing great. I regret for not paying enough attention to the enemies before, they look so cool and funny when they throw the broom and running away. Keep up the good work!
