I've tried giving this game a chance 2 times now. To me it's just a visualizer software that reacts to the music with merely particle effects. I would have wanted the enemy patterns be spawned in sync with the beat to make the game feel more reactive to your music (Tried different genres: metal, house, techno, ambient). Right now it just feels that the music and gameplay are in completely different layers and that doesn't work for me.
One could argue that there is some spawns reacting to the music but it doesn't feel that way. Often times you get bored and frustated when you start thinking all the things the game could have been. The spawns are too vague and unresponsive. I feel the main intent in design was to analyze the song length, create some sort of an enemy buildup into that timeframe and then spawn enemies with an intensifying interval towards the end. It's not a really elaborate system but a really generalized one. It doesn't feel reactive to the music or feel particularly interesting.
Here are a few examples that I wanted to see:
*Having the enemy sprites pulse to the beat at times and giving you extra stuff if destroyed in a swollen state.
*Having different enemy types pulse to different beats in the music.
*Having certain archtypes of beat sequences built to the system. For example in house music the rythm, buildup and lead are quite predictable, those could be used as standardized information and made into gameplay events.
*Every hi-hat spawning a small single enemy from a corner starting from top left and ending in bottom right.
*Every bass hit it could spawn a round pattern of small popcorn enemies etc.
Maybe if the core gameplay were more engaging, I would not have cared about enemy beat sync, meaning the lack thereof, that much. Right now I don't feel like it really holds it's own though. It feels there are many enemy archtypes that could be used to make the gameplay more engaging and less predictable.
Also the enemy sprites look clumbsy and lack animation which gives me a somewhat unfinished feeling while playing. They stick out.
To me this game was not enjoyable due to lack of polish and expectations not being met.
