I think some cool Achievements that could be added to the game are timing based achievements ex:
Golden Star (crusade)
Successfully get 7/7 golden timings.
I think something like this would be cool It would encourage the player to get a fast time and to work towards getting a golden time. This would also be a super rare achievement that almost none of the player will unlock, but the best.
Yeah that’d be a good achievement. We also wanna add some that encourage playing differently, like “dont get hit by any bubbles” on Kraken and “don’t shoot at all” on Execution
