You need a native English speaking proof-reader:<p><pre><code> You can open other islands
by solveing a tasks in alredy
opened.
</code></pre>
I'm not ragging on your skills - my natural language skills are limited (to say the least) - but you need some assistance on that one. For example:<p><pre><code> You can open other islands
by solving tasks on those
already opened.</code></pre>
