Hey!
Nice game with good old arcade vibes, greatly supported by the 8 bit sounds.
What I liked:
The theme is met well and he small mouse was reacting quite good to the input. Also I had to find out myself what different parts of the river do and how they interact with the mouse. When I finished my run, the leaderboard actually encouraged me to try a few more times to beat my own score. The graphics are nicely done and together with the UI, they fit together very good.
What I was missing:
When I was about 125m down the river the river was not rendering completely anymore, so I just saw it starting from half the screen, which basically made it impossible to see if stones were coming up etc. Now, that may be part of the game to make it harder, but if not, then you know it now :)
Thank you for committing, letting me play and keep it up!
