Nice! Sorry if it was too detailed or nitpicky, the game is fantastic! Haha. I was just kind of writing thoughts down as I was playing and things i noticed. Haha. Its a very solid game! It has a great core loop and was really fun! Most of my suggestions are small simple things i just noticed. Haha. Really great work!
That makes sense about the time pressure vs upgrades as an option, but a dedicated end screen would be nice or maybe even a small countdown before the minigames start to keep that time pressure vibe. Haha.
Really great work though! Keep it up!!! :D
