Jak sent this my way and I really liked it. Peak rainy day vibes and the dynamic diagetic audio is a real nice touch. Took a sec to figure out how to interact with everything but was well on my way after giving it a moment's thought. Music is real nice too. However, putting in something to point directly at the hints from the icons on the bottom row would be handy as I didn't notice that until someone told me.
Yeah I'd pay for this on Steam or summat, and I guess you could release map packs after that fact if it's a success. That'd be cool.
