Glad I went and played this myself after watching Indrah's stream - because I -DO- like puzzle games and I quite enjoyed this.
I like the art and presentation, it's very charming and consistent. I feel like some areas need a little polish, but given the time frame and the amount of art, that's understandable. I like the concept, it feels very unique and fresh! I've never played a game with the same concept and the final fight was an interesting blend of the puzzle and the combat.
A few things to keep in mind if you plan to come back to this!
* Change the font. It's very hard to read in large bodies of text. It matches the aesthetic of the game, and is fine for title cards like LEVEL CLEAR or headers on the tutorial boxes, but it shouldn't be used on dialogue, tutorial text, or anything with sentences.
* I'm not a fan of some of the sound effects? I can't place why, but some of the slide whistle sounds were a bit grating. Maybe it's the volume of them. The Leech turn sound cutting into the music got on my nerves a little too. I was enjoying the little bop! Get out of here, leeches.
* After beating the game, it offered me a photo album, however it crashed when I tried to view it. It could not find "Art_8.png"
* Some QOL adjustments. Buttons mapped to skip a turn and the colour map for sure. I'd even go so far to say to just have the colour map displayed on screen somewhere, if you can find a way to do that. You gain nothing by hiding it in a menu since the player can look at it whenever they want.
* You miss too much. A lot of turns are wasted just smacking leeches. Rocks are the most efficient, but there's not enough of them. Maybe having rocks respawn (since the leeches do) or giving the player a starting quantity of rocks will help offset this.
* FINAL BOSS - I didn't like that the colour map changed without any indication. For how long the fight took, I knew the layout well and then it suddenly didn't work. I was very frustrated. Just adding a line of dialogue or some sort of popup saying the boss rearranged the ground or something idk. An indication so the player goes "oh something changed? I'll check the colour map!"
* A turn order display for the final boss might be nice too, so you know when he's going to reset you and you can plan accordingly.
All in all, lovely work! I really enjoyed this game and can tell a lot went into making it a complete experience. Good luck in the jam!
