I didn't know it was possible to make a 10 second souls-like, but you managed it! I alt+4'd with -14 lives :(
In seriousness though, you somehow managed to recreate 4 classic games in one week. I was impressed. Teach me your secrets.
The bullet hell game, duck hunting game and limbo game (lol at that one falling block) were really cool, but the mario jumping star one was kinda broken. I couldn't successfully wall jump up to the star and not being able to use the cannon made me sad :(
All the graphics and amount of work that clearly went in was really amazing!
My favourite submission of the ones I played. Good job!
