Feels polished and fun!  Probably would be easier to play if you made the bottom the down arrow, the middle space or right arrow and the top the up key.  Then again easier isn't always better xD  Nice graphics and music too!  Great work! :D

Nice game! I included it in my Music Game Jam compilation video series, if you’d like to take a look :)

The game seems to have some sync issues, it feels like it's almost there, but can be perfected. The music is really nice though! Also, I find it interesting to concentrate on a single pattern: once learned, it's great to feel in the "flow" of the music.

However I had two main problems: the first is the key position. "Up" being at the bottom… That's quite confusing!^^ The second one is the instant game over. I feel it to be too punitive, having to start over again and again at each mistake is frustrating.

But rhythm games are hard to make!^^ And this is a pretty decent result for a game jam. Congrats!

Beat Defeat is a really cool idea. I love the neon theme you got going,it's great. Really gave me that Osu Mania/ Stepmania vibe. The only criticism I have is that (it could have just been me that was bad at it) some of they keys were out of sync with the music.

It looks like a good start. The beats don't synchronize with the bgm, though? Also, is it the same loop forever? It needs more variety in my opinion...
