Youtuber Zontry was one of the first people to give ERSATZ a chance, and his final video review for it went up earlier this week.


Despite a slightly old script (I posted some corrections in the comment section of the video), it's another super positive look at ERSATZ, which is just fan-bloody-tastic!


Also today, I uploaded v1.44 with a couple of small fixes for the Boss rush mode 'SYNTH RUSH', where the game would crash if beating The Neutralizer boss under specific circumstances.

ERSATZ v1.43 - Halt Foul Bugs!

Youtuber Peppage pointed out a minor crticism in his video yesterday, which I have now rectified with this update with the help of Klianc09! Well you can't say I don't respond to feedback ;)

I fixed a few other things found as well along the way :)

ERSATZ v1.43 Patch Notes

-Level 02 'REGULATION' - Optimised drawing of falling icicles

-Level 04 'RESPIRATION' - Stopped slamming from triggering when trapped in a Catcher Bubble

-Level 05 'REPRODUCTION' - Fixed a number of pistons where you could or would not get crushed

-Level 07 'TRANSPORT' - Can no longer get through forcefields when in invincible state

-Level 07 'TRANSPORT' - Stopped slamming from triggering when stuck in a Detainer CEL

-Level 07 'TRANSPORT' - Should have fixed issue where dying after defeating The Neutralizer boss battle would cause the music not to reset after continuing

-Level 08 'SYNTHESIS' - Can't be healed after dying between final boss phases

-Can no longer dash through forcefields in Type Gamma

-Fixed all known spawn issues where players could take extra damage outside of their own control
