It seems that if you wait some time (think it was like 80 seconds) then the music speeds ups. If you then take around an extra 70 sec, there's a cat coin that chases you and if you touch it, you're dead.
There's also grabbing items when the big cat hides, it gives you bonus points. Maybe even a challenge for getting X points in the first stage.
And lets not forget about getting rid of the cats (either with a door or a bell), you can even take several of them in a row. (There's no address labeled for this yet though)
I think you could add another achievement for breaking a string and not dying, or not using those special doors and beat a particular level. For what it seems, the code for that is level-dependent, so is not easy to make it to work for any level, so is fine to just make it level-dependent.

Second of all, I had a few achievements triggering in a wrong timing, most importantly the level 1, level 1 again & some of the Gosenzo's one. I was wondering why didn't you used the address 0x7b, which determines when you beat a level.
I'll try to look for addresses for the other achievements suggestions. Also, I was thinking on having an achievement for walking on the roof (but I would prefer to walk some distance before it triggers). I was also thinking on adding a leaderboard for most points on the first level too and maybe another one for most points at the end of the game...

Yeah, I noticed some achievements were getting triggered at stupid times. I updated a few achievements not long after I saw that you earned some of them. I figured out why the Gosenzo achievements were triggering. The note for the coin was already in there, so I assumed it would be fine to use by itself. Turn out, it goes all over the pace during the bonus stage. I think they're fixed now. I also think I fixed the level 1's achievements too.
-edit-
I just looked at a recent player's earned achievements, and I'm very convinced that it's all working correctly now. Also, I think some leaderboards for this game would be great! I thought about doing that, but they seemed a little complicated to implement, so I just focused on the achievements.
