@ArmaniAh, I failed to kill any birds with stones with my V2's
R1 - Still not quite intended and once again avoids a trick I intended. For V3, added some steel in the upper right area of the exit platform.
R2 - Your first solution is much closer to the intended than the second one, but both are still pretty bad backroutes nevertheless. For V3, the only change is OWAs added on the exit platform. I'm not quite confident that this fix is sufficient to eliminate any remaining backroutes, particularly as I'm very certain this will be the most problematic of my entries to fix this LDC
R3 - Wow, great find here with the extremely cheesy start which I absolutely did not consider. V3's change is not really noticeable, but I just shifted the wall and its connecting floor over one pixel. Just like with R2, I honestly feel this can still be backrouted, but well, I didn't really do any thorough testing for backroutes before releasing my V3's
