here's a translation tip:
when you end a level in german there stands: "Dem Ende einen Schritt nähergekommen... Vergiss den Upgrade nicht!" --> it should be "näher gekommen" and "das Upgrade"... ^^
If the "anti-poo"-improvement is supposed to make the poo disappear - so it doesn't work, at least for me... if it's on the other hand intended to just provide that poo won't make you slower, so I'm sorry and disregard this comment^^
nice game, I like it. You get less chance in changing your strategy, but it's ok^^ - the only failure I saw till now is that it's "PanzersChock" not "panzershock" :)
Well, the game's ok - but way to easy...
In addition: It would be nice, if the boats would be able to tackle each other.
Further, the crashing with the bonds is kinda buggy - but in general, ok!^^
