I think that this did a good job of expressing what it was intending to express. I don't think I quite managed to get to the extreme purple and yellow shown in the third screenshot here, but I did get into territory that felt like the effects I see when I get a migraine :D

As deertears says, impressive shader work!

Hope you've had positive experiences with Godot - always good to see games made with F/OSS tools!

very cool shading and music! 

I went until "trip lvl. 6" and fell through the ground after eating an "anti-shroom", I'm guessing the shrinking back upset the physics... or the intended ending was to hover forever in the void with stars. 

Either way I like it.

Really good shader work here. Never done drugs but I enjoyed this “search in the grass for psychedelics” simulator. Unfortunately my laptop’s not super powerful so it started to tank in the later game, but the vibe is very strong.
