amazing game! spent hours on it!!
some bugs i found, if it helps (version 3.0):
- downloading worlds (as in, exporting the .tinyworld file) doesn't work for me
- you can see through ramps in certain angles

- rain passes through solid blocks

- in Window mode, i can't use resolutions that aren't in the aspect ratio of the monitor the game is in (example: if the game window is in an ultrawide monitor, i can only choose 2560x1080 or 3440x1440).
- when switching between column types, i can't seem to find the four bundled column option. it only shows up with auto build on. when i try changing it manually there seems to be only single column and the double bundled column.
-i can change intensity of light bulbs that are behind solid objects. this is annoying because i have to be extra careful when mouse scrolling cause i might accidentally target a lamp i'm not seeing and screw up its brightness level
- bright environments (specially in daytime) make it hard to see the interface.
