I played in this version on slow old notebook.
Game is works fine, but found bugs:
After throw coin, is rotated after landing longer, and sometimes don't stop rotation, playing loop-sound always.
If come to interior and back to exterior, coin sprite is disappear, but i still pick up them
I think is happens more often if current scene some laggy (how to see FPS and update dt in the game?).
Throwed coins on ground not saving when pee (this coins disappear after loading). This on normal PC too.
Coins can fall through barrels and concrete barriers (not bounce like with walls and crates) and stuck there, then we cannot pickup them.
One time i pickup non-encrypted radio from body (2 guards with jokes). Then saved and after loading again this body blinking and again pickup same radio, but counter radio in inventory not increased.
I checked it, is happens if we not product 2 encrypted radio.
Sorry for typos and grammar.
And you have good music composer. I listen track 'music_exteriores.ogg' many times, nice stealth music.
