The gameplay is really interesting and makes me truly feel the tension of the time flow. Many possibilities can be found during the experience, for example, more efficient memorization, proper spot to place the item (so u can drag them faster), different sequences of handling tasks, etc.
From my experience, I am very likely to finish the stamp task first but forget to accept it and make stupid time gaps. But once I tried the game multiple times and reach a higher score, I really proud of myself for the progress., which makes the game really addictive as you always want to achieve a higher score.
The artwork and animation are really cute, and the sound effects fit a lot. Nothing to say about that.
A little suggestion would be on the difficulty. For me, it seems like the game gets harder a little bit quicker. During my playing, I still did not get used to doing a 4 pages task and it came with a different color or type of stamp. Also, I think declining a task really takes a lot of time as you need to find the big stamp, colored it, stamp it, and submit it. Another thing I wanna mention is that there are some 5, 6, or 7 pages tasks that only grant 2 coins which makes them less acceptable. The Player has to choose whether accept the task or not but declining one is also a big cost on the time. So, if I were the developer, I might make the coins increase more time, or make the coins of each task more ratio to the number of pages: it might be 1 coin for 2 pages, 3 coins for 6 pages...
Overall, I like this game very much, and I believe it can be better if there are further patches or updates.
