Cool game, needs work though

This seems pretty bland but not a bad start. Aside from just collecting all the coins, there is no real challenge to this game or real risk of losing aside from if you close the game or browser you are using.

The sound effects are basic and the game itself can be completed in a few short minutes. Not really much else to add on to aside from adding background music I guess?

Overall, it's not bad, just boring.

I'm sorry but as a game this is completely uninteresting. I was about to just give up at level 4. After that I got some hope for an interesting development, but no. No mechanisms or thought at all. The most interesting thing that happened was that I got to press a button at the last level, and the fact that this was the most interesting thing says a lot.

Creating a game is a bit more than just get the code to work.

you should add enemies to avoid in the sequel if it comes out

Prevent the player from stepping into an empty tile (so you need to find a way to hit every coin without backstepping) and it might be interesting.
