Love the art style and music! And a simple approach to this game! A very polished game as well.
But, in contrast with the cute art style and music, the gameplay is very brutal, it requires a lot of knowledge about the game just to play pass through all the levels. If I'm not missing something, once you make a bad decision (like buying too much slot for the monster or buying too much monster but not enough slot), there have no stepping back but to restart from day 1.
Just like Sekiro/dark soul boss rush that has lots of RNGs involved without any checkpoint.
I think giving players ways to refund the monster for meat and letting players cancel the buying monster windows can ease up some frustration in gameplay.
Personally, I enjoyed it.
