I seriously don't understand how anyone can create a game like this in 2 days. The game has:
1) Procedural world generation
2) Two types of opponents
3) Treasures and islands where you can improve your ship or sell items.
And perhaps there is something else that I haven't seen. Excellent art style and interesting gameplay complement each other.
Of course, there are some issues, such as the fact that enemies appear too often (at one point I was chased by 10-12 enemies). However, these are all non-critical problems. After all, a game made in 48 hours looks like a game that took a week to create.
Great game, worthy of being in the top three
