I am honoured to have made it to Round 2! Thanks @EatMe for such a clear and useful feedback, I am sure incorporating it has made my mix significantly better. Let me address the individual points:
The superwave p8 synth has lost a bit of its staccato groove: I have reintroduced it with a subtle 16th note tremolo effect
The synth tracks do not have as much momentum as the original.: At first the synth tracks (mainly the MauSynth) seemed too dynamic, so I may have compressed them to tame the fluctuations. I have dialled that back a bit now.
The intro (gainstaging) is beautiful: Thank you

The snare drum is too snappy in its attack time and needs a longer initial attack peak: Agreed, I have overdone it with the transient shaper. It sounds much better without it.
The snare drum almost sounds replaced with a 808 snare, losing the original snare drum noise color and length: Absolutely correct, I have somehow lost the original snare during the mixing process. Now they should be much better balanced.
The snaps have been mixed in at a too low volume to really hear them (on speakers).: Should be better now.
Here is my revised mix: MC088__EatMe__Shift__Zajus_R2.wav
Good luck everyone to the second round!
