Great music, and great sounds!
Some bosses' attacks feel a little cheap (like the garbage coming out of the bag and then bouncing or the low drawer one on the first boss)
The aesthetics are pretty consistent until the second boss, where is feel like the stage was rushed.
The attack from the player coming out of the straw is a cool detail, but in terms of game design, Is always expected for the attack to come from the center of the playable character, this, with the small platform in the second stage, makes hitting the rat boss a little harder than it should
I understand the fact of not resetting the players health after defeating a boss, but the character can only take 3 hits, and you can't continue from the last boss you fight, that makes the game way harder than it should be, Reseting the health OR allowing to continue from the last boss would fix that issue.
The use of the theme is good, but pretty common among other entries
In game transitions are a little rough.
I really try to beat the rat, but I wasnt able.
Super Charming game!
