Fun game with progression being the core mechanic! Although I must say I found it quite hard to progress early on - kept dying! haha
Well done!

Played your game here, it was fun~

This looks like it was inspired by Zelda. I was having a hard time killing the enemies at first but after I got enough gold, nothing could stop me... Well the enemies were tough to dodge, and kept going in a direction I couldn't attack, like lower right or upper left. I enjoyed the shop and buying upgrades but I didn't see an end game. Nice work!

Damn this one definitely dishes out a beating on you, but still pretty fun!
I like to think of it if Dark Souls was for the Atari 2600

It's a relatively big game for a single jammer, It was a little to hard for me, but I liked the upgrade system, it almost feel like secret or an easter egg haha Overall really good
