Ah... and you already hit my game with a bad review. Once this problem is resolved, PLEASE CHANGE YOUR SCORE. QuestORama's rating has already suffered enough from people who decided to use the review process as a means to submit bug fixes, but NEVER came back to update their review after their problems were fixed. This is VILE thing to do. It's a free game and represents hundreds of hours of my life. At the very least, you should allow your issues to be addressed here before trashing the reputation of my project.

Check out the new version, the height issue should be gone. Maybe. I don't know, as I never saw it in any version. But in 0.1.8 I lowered the player's capsule height to get around bumping grenades placed on a ledge well hanging off the side. That didn't help, but I didn't see any changes either, so I forgot about it. In 0.1.9 I changed it back to the default height of the capsule the game has had since the beginning. Again, I didn't see any difference, but maybe you'll see a change.
I was able to fix the "bumping" problem by instead making the player's capsule skinnier. Now it's much easier to place grenades on the edge when climbing up. Of course now, thanks to slow-motion and swords, my new favorite tactic is to just fly directly at the enemies, deflecting bullets with the sword and running them through.
