Neat little game!
I think the art style is very strinking and gives the game a really cool, dark feel. I like the layout of the dungeon with it's secret tunnels and fake walls, it felt cool to explore (although those spike traps on the floor at the start are EVIL)
I think the NPC's dialogue should stay more time on the screen, sometimes it vanished before I could even read (also sometimes the text would outright display TEST, but after a few resets it fixed itself lmao)
As a little trial and error puzzle game it works well and it's fun to play, congratulations!
(Also, the deaths are pretty funny lol)
