I think I played this game much longer than I should have, the only reason I kept moving forward was to see the look of each new level because the textures changed. I think I made it to Level 6 before I assumed that this game did not have an ending.
The game has nice graphics and atmosphere, and the added touch of procedural generation is nice too.
If it had move mechanics other than navigating around the baddies, I could probably play it for longer.
I noticed a bug that after you die, you can still move and press space to hover like something out of Minecraft Creative mode.
