Thanks for your comments hygge! my paragraph-by-paragraph answer follows:
I've for a few years wanted to make a "biologist game". Then the idea collided with an already-existing post-jam platformer, and they fused into EMUUROM.
Snail shortcuts are tHE BEST. Also, there is a map screen, but its button is currently only told in one of the 'tombstones', or virstanpylyväät.
[it's the S key]
I'll consider adding more holes to the ground (through which the scanline is seen in the secret tunnels)! That might change the aesthetics of the tilesets considerably, tho, which means design work (note also: i am lazy)
Slipperiness of movement is mentioned enough times already for me to do something about it.
There will be a few emuuroms that are designed around pausing :)
The "future path" phasing is indeed just a visual thing
maybe I should add an easter egg to the endscreen as well...
:D Luckily, there is indeed more to be found in the demo, see my answer to your second message :>
