This is so good! I love the options that open up being able to use water to clear tiles, it takes quite a punishing tight grid and allows more skilled players (not me) to expand their options. Mixing a match 3 cascading pieces with polyominos truly great idea.
A few nit picks (the game’s great these really aren’t a big deal) It may end up being a bit burdensome but for such a tight game the shape order being randomised can feel a little too swingy, especially with the pieces varying is size quite a bit. I don’t think a determined order would be better but a randomised order where you get to see at least the next shape coming up could be a good balance. Also one of my favourite parts of tile laying games is counting points, especially when there’s more complicated scoring than pure size. Every time I got my score I hoped the score tracker was only tracking absolute sizes and not bonuses from mountains etc. definitely a personal thing but a Balatro esque point count up could add a little drama to the end of a stage. Obviously players can just count stuff themselves idk I just like to watch the number go up (especially with placement specific bonuses).
Really impressive game even outside of it being a game jam!
