This had a big update today as well, with new modes, characters, arenas and some other gubbins: https://www.gamespot.com/articles/super-bomberman-r-update-out-now-for-nintendo-swit/1100-6451291/
£29.99 would be too much for what I played when I had this in March and April. I don't really think that what's been added today compensates for what I feel is quite a poor game. In other words, at thirty quid, I don't think anybody should be tempted. The Switch has come along so much in the last four months, nobody needs to settle for Super Bomberman R as an alternative to Breath of the Wild anymore.
