I used gemini for the general art as well!

nice! I was personally surprised seeing scores roll in that were lower than mine, since I had played the level so many times while debugging haha.

Best in the system now is 17.1s and it must have been a near perfect run.

thanks for the traffic everyone -- definitely hitting rate limits on gemini already so if it doesn't work please give it a try later in the day or try the example.

Apologies for the inconvenience! If anyone on the gemini team can help out, please lmk (email in bio).

Thanks! A few friends have starting using the generated digis as profile pictures because of how recognizable they are. I was definitely surprised at how good the models had gotten.

Thanks! Like another user commented below, I think the appeal of the pixel art sprites is that at a lower level of detail it can feel really accurate. 10 different real life red jackets can all end up as the same pixel art representation but each person would recognize it as their jacket! It feels like a form of compression.

On prompting, you can get most of the way there in AI studio on Gemini 2.0 Flash (Image Generation) Experimental by uploading a picture and asking for "a high quality detailed pixel art sprite of this character." Most of the backend annoyance here was iterating to improve prompt adherence (characters not facing the same way, outfits changing between frames, etc).

Thanks! There are some content filtering rules via Gemini, but if you got an error on Trump I'm guessing it's an issue with the image generation rate limit getting overloaded.

I've been monitoring some of the image generation progress for game sprites for a while and was really impressed by Gemini Flash. This demo lets you upload a picture and turns it into an animated pixel character (a lil digi gif that you can download). I chain together the pixel art frames and insert the player into a tricky platforming level.

video demo: https://www.youtube.com/watch?v=EK7z-HltssE

api usage: Unfortunately Gemini Flash 2.0 image Gen has really tight API limits that don't scale up for paid tiers -- if anyone on the team sees this and wants to help me out, my email is in my profile or you can reach me at hello@lildigi.me

level stats: For the speedrunners out there, the fastest glitchless times I've seen around 17-18s.

stack: cloudflare pages + aws lambda + gemini

happy to answer any questions!

Really creative game! Great work. Echoing the suggestions in the other comments to provide some clue on the number of letters.

Is there a simple way to download the portion of the data that was breached for just our own account?

I've switched providers and deleted my LastPass account after this last breach but getting to see that would make it a lot easier to understand risks.

Implemented a history button after completing the game that should make it easier for you to share!

this is a great idea, let me see if I can make that easier!

Both great ideas. I'll look at the calendar-like feature.

Stats would be cool, I don't currently collect them but will think about adding them. Thanks!

interesting, thanks for flagging -- this looks to be a parsing issue when ChatGPT occasionally returns guesses in a format different than the one instructed to. I'll give this some more thought on how to fix...

Some technical notes. Even for something like this, the OpenAI API can be expensive - there's a few decisions I made that keep costs lower.

1. I cache guesses and responses in Redis when I first see them, so I don't need to hit the API for duplicate guesses (which are common when lots of people are guessing the same movies).

2. Emoji order doesn't matter (I apply a sorting to guesses).

3. Guesses are not path dependent, with each guess being treated as completely new. This is understandably annoying when GPT guesses the same incorrect movie multiple times, but it drastically improves the cache-ability and keeps me from hitting my API limits.

country flags are enabled - the search displays the Italian flag if I type in "italy". However if I type "italian", it doesn't match to the flag unfortunately.

Ah that's annoying! I've swapped it out -- thanks for catching it.
