MSX game developer N.I. got very busy coding towards the end of 2019, releasing a classic puzzle Lemmings type clone for MSX 1 called Isitar7. Your objective is to guide the 100 mice to the exit. You can assign the following skills to the mice:

Climb: climb a wall.
Parachute: use a parachute when falling.
Bomb: explode and destroy surrounding blocks.
Stop: stop moving.
Ladder: make a ladder.

Dig 1: dig sideways.
Dig 2: dig diagonally down.
Dig 3: dig down.
Back: return to the title screen.

Controls are via the keyboard. Arrow keys: Move the cursor, [Z], Trig-A: Assign the skill to the mouse. [A]-[X], Trig-B: Select the skill.

If you are a fan of these puzzle type of games then you will enjoy playing Isitar7. You can play online or download free at:
