It's a good first game to get accustomed to game making and trying stuff out, in that regard I think it's a fine project, but I think it doesn't hold enough entertainment value to keep playing for more than a few seconds as it is now. To expand on this project, you could add sound effects, make more interesting sprites for bonuses and enemies and diversify the game in general - more movement options, different types of enemies, levels, and so on.

Unique concept for an avalanche clone via auto walking and clicking to change direction, but it makes for a frustrating experience.
