All valid feedback and great points. I actually wanted to include an option to restart from the round, instead of the game ... but the coins were tied to a global and I couldn't figure out how to store that at the room start to access again if they selected restart round again without them just keeping all the cash they collected. I think ... just sitting here and typing it out now I have a few ideas and could probably find help in the GameMaker community, but it was one of those cut for the jam deadline things.
The pickup signaling it was going to disappear in like five seconds or whatever ... such a simple thing to implement and I feel silly for not thinking of it when designing. Excellent suggestion.
Thanks so much for playing and the great feedback.
