Love a typing game!! I definitely forgot about the shop and nearly did the entire game without upgrades lol. Half way through the last one I realized the error of my ways. The only feedback I'd give for a game like this is that since you have to type sooo many words, the sound effect for completing one correctly got a bit grating. I have heard some advice for gamemakers to alternate between sounds or even modulate the pitches of the sounds a bit so that they don't register as so repetitive, maybe something to look into if you expand! Overall I really enjoyed playing your game and I thought the art was cute too :)
