Huh, this game is pretty interesting, being some sort of fusion of Conway's Game of Life with Vampire Survivors! More so that that, though, I was really surprised me with how much my impression of it flip-flopped!
My first impression wasn't that great. I'm not really much of a fan of idle games in the first place so there's that, but I just felt like the game was pretty mindless. There just didn't seem to be any sense of strategy or feedback to anything I was doing: I couldn't tell what the enemy was going to do next, so all I could do was hope for good luck and use whatever cards were given to me and watch the little guys go at it, which with the limited game jam graphics, wasn't that appealing. More so than that, the game felt really slow at the default speed, but I wasn't sure whether to speed it up since I felt like since that was the default, there must be some sort of micromanagement I was supposed to be doing, despite there seeming nothing to do.
Eventually, however, the game started to grow on me! Not only did the game start to introduce unique and challenging waves to watch crash against your blobs, like big rows or columns of enemies, but I also cranked up the speed to max which felt a lot more appropriate. While the visual effects weren't dazzling, the game did have all the critical feedback necessary to showcase the various perks and powers your slimes were picking up, so it was satisfying to watch them grow. Before I knew it, I ended up playing several times to take different routes of growth to see how it played out!
So yeah, in the end, I think it's a pretty cool concept and certainly has some merit, and considering that's the main goal of a game jam, this is a winner in my book! If it were just a bit more juicy and made some subtle changes to things like the default speed and the frequency of unique challenge waves, I think it'd be a hit! It reminded me a lot of playing Plague Inc, where you need to decide how best to grow your virus to maximize aggression while remaining covert and other factors in a great balancing act.
