It's hard to move the tank and change direction, but that's what makes it fun.Tank can move forward if you get caught in something, and there's a correction process for the wall, so try your best.
It's good that the last enemy escapes in a retrospective rule.
Thanks for your comment. Hepatoorn needs multi-cartridges, so I'm not thinking about a standalone p8 right now. If you can use a browser on a handheld game machine, please play with the browser version of Hepatoorn.
