violet sinew
Not a bug itself I guess, but when you respawn, you do not preserve any Invulnerability Frames you had when touching the checkpoint while receiving damage, so what's happening here is that I had 2/4 of the last heart, took damage (1/4) and was able to touch the checkpoint and escape because those iFrames. Then I died and respawned with the las 1/4 of heart I had, but without the iFrames, so I died. And died. And died...
