Jasper!

Jasper the mouse must face 22 screens in this platform puzzler. Tonnes of
objects are placed throughout the game, and each has a specific use. You
select these using the 1-5 number keys, which tells you that only 5 objects
can be carried at a time, which makes for a certain degree of backtracking.
The screens are full of adversaries like cats, spiders and wasps, all of which
must be avoided, as contact loses you a life. Methodical planning of your
route before you start, and inch-perfect timing and key-pressing once you do,
are essential for progress – charging in headlong is unlikely to produce
anything but a dead mouse (and a dead keyboard after you hit it)

Jasper!
