It's obvious that a lot of effort was put into this game but... since it's not your first one... it has A LOT of flaws.
1. The screen is tiny... Game doesn't look bad but well... I can't really see it close enough.
2. You've put this much effort and still you've used random font from MS Paint? Or something that looks like it.
3. At the beginning it feels like cutscenes interrupt like every 10 seconds of the gameplay.
4. Controls... pick up with Enter and extra key for shooting upwards? Really?
