I know it's an old game, but can anyone help me with this? The game always crashes in the final stage and I think it's my computer's fault, but I can't figure out what's causing it.

I was playing that Tenshi platformer for a while today. It's really fun and the game play is solid but there are a few issues so far. I noticed a lot of Tenshi's sprites aren't fully drawn. You can easily see the quality of her sprite go right down on some frames. I was OK with this as it generally only happened during particular moves and the worst that happened was her bow disappearing.

Then I got to the 4th stage boss Yuugi. What the hell? Half of her sprites are of a different character/boss! Not even the good quality sprites of that boss! Her own sprite drops in quality for half the time her sprite is even used (so 25% of the fight)!

Is this just an isolated problem or does it keep going downhill from there?
