Nice little 😉 game. Also the fact that you made all of it yourself and with Stencyl is admirable.
Gameplay
The rotating shoot mechanism works well for the game. Also no button smasher because there is already shooting for you. Although that also takes away bit of gameplay by not having to shoot yourself in time.
One hit one kill is challenging, but also annoying if you have to go back to level 1 when you already have finished that level 😅. The first levels are fairly simple but you have to go through them again and it is not that fast. Some kind of waypoint system might have been useful.
Enemies are getting harder and harder so you have to pay more attention instead of just shooting everywhere like in the first levels. Yet you try every time to get further and that is a good sign for a game.
Graphics
Simple but effective for the game. It all fits together. And all self made.
Audio
There is music and sound effects and that is always better than no sound. Some more variety would have been nice though. They are simple tones. Maybe for an update.
Theme
Upgrades fit in. Enemies getting stronger too.
Devlog
Good comprehensive devlog with images . This shows well the working methods and insights into the game development. Nice!
All in all a fun mini shooter 🙂!
