I don't know if it should be removed, but if it's useless, it shouldn't be part of the dice roll. If two out of three of the cards are warm soup when I have full HP, I'm going to feel ripped off, especially if it keeps happening.
I don't think "Salvador" is a thoughtful person. When this game was first posted, I noticed how targeting turned to garbage when the game was sped up. This is a sign that the dev doesn't know what they're doing and doesn't care to learn or do the job right.
When you think about it, many/most of these games are made on platforms that require little technical expertise to use. This game is little more than a quickly drawn... well... tower defense game. There was little imagination put into it, the targeting sucks, and the dice rolls are for things that are useless.
Maybe bad games were okay in the Flash era, when everything was made so easily, but when games and gameplay on Itch.io compare unfavourably to scammy mobile games, it's a sign that someone with less talent and more delusions is inflicting their lazy, privileged mediocrity on anyone who'll put up with it.
It's too bad. I usually like good tower defense games. I guess that much hasn't changed, but it seems like this game should be fun. I should probably hop over to Crazy Games and spend more time with a certain wizard tower defense game. Progress may be slow and failures plentiful, but at least it's professional and without glaring flaws, like missing stores for currency or a downloadable version that still doesn't run properly, as if it took some sort of ability to code to make.
