I
FINALLY cleared TwinBee Yahhoo! on Normal!
This game is very fun, but also very infuriating due to the bell system and rank (which seems to go down somewhat when you die, and is also probably influenced by survival time).
Although you get more points by collecting power-up bells (option, normal arms, etc.) when already powered up I didn't play for score but scored 2.4 million.
I once lost my last life to the very last enemy (the black robot) on the final stage, which was very saddening after all the tension
Although I had extends set to 300,000 and 700,000 points(same as console versions, arcade defaults to no extends, played on MAME) and lost all my lives along the way this has to be one of my hardest clears yet!
I haven't beaten the whole game on Practice yet, but on Practice getting past Stage 3 requires a 50+ bell chain which will surely take some practice.
A quick tip: if you have Gwinbee at the fight with Ace in Stage 4, you can take him down very easily!
Stage 4 also has my favourite boss in the game
