Yo. Nice. This little cinematic is funy. the game is short but you have a good physics.
Nice idea for all new enemis at each level
For recomandation Pennigar said all. But if you want to continue on shout them up style, I design the R-type series an Parodius (if you duno). You can find a lot better shoot but for me they are the most inventive. You can find a lot of idea like maze and changed traveling during game.
Thank for your work and your game. Cya.
