Extremely well done on implementing all that in just 4 days, the game was smooth and really fun to play around and control.
it is very similar to Minecraft, which is not a bad thing per say but there might have been a way to expand it further.
also i feel like the lava could have rose just a bit quicker, i felt like i could take my time.
well done!
