I really like the puzzle involving the numbers. I felt smart when I figured out the first digit was the subtraction and the second two digits were the addition!
I didn't understand the puzzle with the colors at all but I figured out a way to clip through the bars and I consider that a fun feature lol.
I had some technical issues such as the cursor not having full rotation and also the cursor escaping my window but otherwise game is charming and I find it memorable. The music was annoying at first but it eventually kind of drawn on me. I guess more puzzles that are clearer and a more consistent theme might be nice. I am not very good with colors though. I liked backtracking to get the buckets because I thought of bringing a bucket the first time so I felt rewarded for experimenting like that. I only got the cake bad ending tho
