Honestly, I agree with you. Room 2's solution is clearly broken. I'll update it tonight to make it clearer.
Also the arrow thing is basically me scrambling around to find a way to input the passwords. Sorry if it made the experience less fun :/
I took another shot at it, since you mentioned changes. Room 2 seems better, but when I beat Room 4, I got this error:
___________________________________________
############################################################################################
FATAL ERROR in Vertex Shader compilation
ShaderName: shd_distortion
D3DXCompile failed - result
at gml_Object_obj_trippy_background_Draw_0
############################################################################################
--------------------------------------------------------------------------------------------
stack frame is
gml_Object_obj_trippy_background_Draw_0 (line -1)
Edit:
Oh, I guess I should also mention the other issues I had: Room 4's key is really hard to read, and for Room 3 I couldn't figure out what meaning of "overflow" would apply, since the normal programming meaning would just result in dropping digits. I also had to use this autohotkey script to figure out the morse code since I have no training.
Well that error solidifies the fact that I shouldn't be allowed to touch shaders.
I'm sorry for all the issues. I can't update the game now, but I'll make sure to keep all of this in mind for a post-jam revision of sorts
EDIT: I looked around and apparently this fixes the shader issue? https://www.microsoft.com/en-us/download/details.aspx?id=35&44F86079-8679-400C-BFF2-9CA5F2BCBDFC=1
Let me know if it works out
