The artsyle for this one is quite cute, and I thought the sound effects were fitting for the style. In fact upon checking your other games I recall I commented that your Kaiju Jam entry one time could do with sound effects, and frankly I think them being added here helps quite a bit even wtih basic sounds.
As for the rest of my feedback I should preface I've never been hugely into platformers, so my feedback may be a little out of touch.
The movement definitely conveys being in a mech, but much like a heavy mech trying to platform it felt a little too clunky, stiff and slow to feel good for me.
And I think having death set the player back to the first level and with no way to regain health to be a little too punishing imo.
This was a cute little paltforming, but one I don't think was for me, good job though!
