Really enjoyable game, and what a nice wee ending, thanks!
I liked how all the minigames were tightly themed to what they were upgrading. The maze game was my favourite but the ones with single input solutions were a little hard to complete quickly. The other two 3D games were a little chaotic but it was fun finding little optimisations like picking up the hammer straight away to hit all the materials as they fall in from spawn to identify the properties quickly.
