oh also about the slime: i do agree that a lot of "slime cache" areas do not reward the player with enough slime to make access to it worth it. (we kind of forgot to add more slime there. and by i guess by "we", i mean "i", because i'm the one who added more slime pickups to certain cache areas). but from my experience playing it, i think it's adequate enough to be able to build enough structures. i feel like i'm able to do a lot of level modifications after getting the hang of dodging macey on round <5 speed. or maybe i played the game way too much during development and i think the game is easier than it actually is.
also, i feel like restricting the player's slime count would probably help with replayability because . uh... the player would have to compromise a little bit. then maybe they want to try again so they can do better on the next playthrough. ..maybe that's fun? actually it sounded better in my head
