this is honestly really great feedback, thank you! ive been considering putting the game on steam and the eshop, so this is all very helpful :D
to address specific things...
> "the time before detonation is, a bit short imo"
yeah, in hindsight i agree. this is one thing im definitely going to increase
> "the greenish skin kinda blocks my reading... and the bonus mino on it might need some design to let the player read what color it is"
that was definitely an oversight on my part, whoops! ill see what i can do!
> "the wave on the stack sometimes blocks sight too, as also mentioned by other players. i see there's option, but i think it could be preserved being also readable with some tweak."
i think im going to just tone it down slightly, and add a toggle for it to the settings. though from my first tests, it absolutely WRECKS the framerate on the switch (for some reason) so i might end up removing it completely
> "static block requiring 3 adjacent clears to destroy... imo is a bit hard..."
it's two adjacent clears actually, from my testing that seemed most well balanced
> "also on marathon, my preference on built-in singleplayer modes would be rather "pure" ones"
im planning to make the "endless" mode way more configurable, including a toggle to disable the static blocks entirely, so i guess there's that. i do want to keep the static blocks in the marathon mode though, i think they make the gameplay a bit more interesting
> "by the time typing these words, i even came up with another bad idea that, being non-static, the garbage mino could change into some color on adjacent clearing."
this actually sounds like a genuinely good idea i will definitely try out!
> "hope there will be netplay some day"
that's the one thing that's outside the scope of the updated version. netplay is actually very time consuming to get right, and it's an even bigger pain on the consoles. i will add online leaderboards at the very least
