Heh! Different use of the word "Ranger." I like your enthusiasm, though.
You should see a green bar above your ship at the start of a run. That's your health bar. (I'll admit, it does get a bit buried beneath explosions. I'll see what I can do about improving viability.) You can take 4 hits at the start of a run with no upgrades. Enemy damage increases during the course of a typical run.
Funny you should mention the in-game devlog! I actually just now pushed a build which fixes the scrollbar. If you refresh your browser or restart the itch app, the good news should now be prominently displayed in the in-game devlog, which should scroll using mouse dragging, the mouse scrollwheel, or up and down on a controller (after highlighting the scrollbox, of course.) This was really hard to fix, so let me know if it works on your end!
I'm glad you think it's that good, despite all the bugs. :D
