Wow, actually a really nice critic and this is something that I'm very passionate about so I feel the necessity to reply you with a long text too lol.
You pointed out a problem that I think is pretty obvious, it is too overwhelming to play. I think the problem came from the resources having similar times of reduction, resulting in a lot of overlaping of messages at similar times.
Also we did not wanted to make the gameplay too long (so upgrades have more meaning), at the end is a jam and we thought that the people might not will want to spend much time in each game. However, a lot of the upgrades we added were a lot to fun while testing between us but can only have value when you have some experience already with the systems. If we have had two hours more of time to try it more maybe we could have adjust it better (or we would have try to add something else lol)
I think I rant more about other things but your comment is 100% an opinion that we will take into consideration not only for this game -if we decide to continue developing- but to other experiences or jam that will try to be part of. Super thank you for commenting! this is the best type of comments a think a game can receive!
