i dunno if the authors will ever read this here, but i noticed a small glitch: when the sprite is falling down, the background is restored in the wrong place and jerks down too for a moment, like this:

and some sprite masks have a few unnecessary junky pixels (also mostly visible over a solid background like the door)

I have found the cause of this bug (missing routine call). Also when exploring it, found yet another potentially fatal bug that only by a miracle doesn't corrupt or crash the game (won't be sure if it's never possible though, so worth fixing too).

These both are fixed now in the new TR-DOS release (check vtrd.in) and in my ULAX game pack snapshot. Also fixed player sprite blinking (disappearing for one frame) when it goes from jumping to falling. There's a short hitch in the animation at this moment, but i think it's still better than blinking sprite. Maybe will be able to fix this too, or the authors will in a new official version...

I completed the game and saw no bugs, what was it exactly?

it's on the pic right here - the background is shifted down (the door is actually taller)
or even better, stand a bit beside the door and jump - you'll see it splitting in two

the other bug is ret when there's a forgotten data address on stack
then by luck after a few nonsense ops a conditional ret happens
but i'm not sure if it happens every time

Hi,

Would you mind sending me the bugfixes? I can forward them to sejuan (the game author) so we can get an updated build.

Thanks!
