I like the premise of waking up inside of a liquid tank as the tutorial but it really should be skippable. The first time is okay but repeats are just waiting games. The visuals and atmosphere (literally) are quite fitting. The cutscene of being flushed into space was an interesting touch.
The controls were pretty self explanatory tho the tolerance for the lever in the capsule is very unforgiving. I pulled it when it was touching green and I got the same death screen. I suggest making the descent go faster (at least 3X) so there is less downtime considering you only have 2 other controls to juggle aside from the lever (I assume the parachute controls)
Assuming you wanted to expand this in the future, you could include some audio dialogue that changes each time you die.
Also, I recognize that flame texture! (balatro godot shader)
If you tab out of the game, the game doesn't recapture the mouse, tho it seems ur already aware of that
+1 on adjusting the turning of the crank so that your whole head doesn't bob around at the same time
