Fun and addictive game! I ended up maxing out all upgrades. XD
I like how you adapted tengnose's sprites into the game and crafted an enviroment that fit well with the style.
The minigames were varied enough and fun to do! That reverse signature minigame came outta nowhere and was pure evil! XD (I hadn't read the game's description and wasn't prepared for that haha)
Good job on the music remix too!
My best run:
