Very cool and original concept, I've never played anything quite like it. The art style is cute and fits the retro gameplay. The connection of ladybugs and dice both having spots is a clever detail, even if I was too dull to realize it until the ending screen when I "earned my spots". I liked the attention to detail with accessibility, such as having descriptions of Ladybud and the enemies, an option to use a more legible font, and even saying "another X damage" when the same number happens twice in a row to sound more natural.
The mechanics of picking dice packs and breaking dice added some nice strategy to the gameplay. The battles were pretty entertaining at first, but started to feel repetitive as you faced tougher enemies. I would have liked more challenge, too. I hope you keep developing it and adding more variety to the battles, there's a ton of potential here!
One technical issue is that there wasn't any TTS output when using Windows Narrator and Firefox. I don't know enough about Narrator to guess the cause, but it would be worth trying to fix. I tried again with NVDA and it worked perfectly.
Overall, very nice game! Great work!
