I really liked it! I love puzzles. Not gonna lie, all of this being done in just 3 days is impressing to me, even with a team of 3 members. I loved the visuals, they fit really well the game. Everything worked well on my end (e.g. I wasn't so hurt by the doorframes as most people were) so I can't give much of a constructive feedback. But I'll sure be excitedly following this project if it continues!
Oh, and this soundtrack is so neat
