I always wanted to make a good point and click game, so here it is :) (I hope it's good!)
You can find the walkthrough in my profile if you ever get stuck! The game is not too short, but its not super-long either, however it's challenging and if you ever get stuck, well, look for hints. When you roll over an object, the description appears in the bottom right corner, which usually gives hints on what to do next!
Also, please note that the first key does not open the first door/chest, so it's not a glitch. Look for alternate ways to open the door!
Hmm, also you note that in the colour combination lock, it is easy to mistake pink with purple. The purple colour is the darker one :)
Once again, if you need any help, there is a walkthrough in my profile! Share your finish time in the reviews!
I hope you enjoy this game as much as I enjoyed making it!
