Simple and to-the-point caravan shoot-em-up. I always appreciate more shmup developers, myself!
Scoring is pretty simple and doesn't give much room from optimisation, but I think it's fine this way. Perhaps adding more bonus candies the faster you kill enemies and bosses could work? The patterns are also pretty simple and sparse while not being completely random, which is nice. It works with the lack of a focus button, in my opinion.
My main complaint is that the bosses kind of have too much health, it seems like all of your shots need to hit and just missing a few while dodging means you won't defeat Flandre in time? I'm not sure, I still need to test it a bit more. Some folks have managed to defeat Flan with leftover time so it may be just me.
Overall good work! Gives me real Sega Genesis nostalgia vibes (<- was not born when the Genesis was released).
