My favourite games so far
Explorem Ipsum: Catacombs of Time by @notexplosive

This is a Sokoban (box pushing, e.g., Baba Is You) style of game that gives you great tools and freedom to solve quite challenging puzzles. The game does let you figure some stuff out for yourself which I think is really fun but if you get stuck here is a hint with a Caesar cipher of 1: Zpv dbo dbssz bsujgbdut xjui uif hmpwf. Uijt bmmpxt zpv up ibwf bmm pg uif bsujgbdut jo uif tbnf sppn. Bmtp hbuifs cpyft gspn uif puifs sppn.

Play time: Quite long
ONLY GO DOWN by @jefvel
.
One button cave diving game with innovative mechanics and very cute music. You can dive, glide and parry the walls with just one button and it feels great. Did I mention how cutesy the music was?
Play time: Moderate

BUMMÖCK by @alec

This is coming for the fans of isometric action time trial games. Gameplay is very solid although laggy as times. It also teaches you a word BUMMÖCK: bottom part of the iceberg (I'm writing this without double checking to test my memory).
Play time: Quite short

My game: Deep Space Photography
Also, play my game if you like astrophotography but just hate it when eldritch monstrosities ruin the pictures of galaxies!

Play time: 5-10 minutes
