My Tester (Finally) played Jumping Jim, and he had a lot of problems with the game, and now that I have addressed and fixed some, I see how much a new perspective on my games can help quite a bit.
1: Why does Jim bounce when landing? It prevents jumping right away and leads to death.
1a: Fixed, landing and Jumping are alot smoother.
2: It is quite tedious to have to start the Level all over again when you die.
2a: Checkpoints are being put in right now.
3: Why can I only aim up when fighting the last boss?
3a: Multi-directional attacking Implemented.
4:(from a passerby watching my Tester play) you need a way to tell how much damage you are doing to the enemies(Last boss)
4a: Last boss Health Bars Added.
5: there should be more sound effects
5a: coming soon
6: you should unlock the next level when you beat a level (beat level 1=unlock Level 2, Beat level 2= unlock level3...)
7: You need more backgrounds
7a: working on it.
OK, before you check the Downloads page, I have not uploaded a new release yet, I will once all of the above are finished.
