Hello uieh,
I like the style of the game, the artwork works very nicely, good job!
Some feedback on the gameplay:
- Always find it satisfying to hold down a button to shoot but realised I was able to stay in one place and kill enemies off screen. Perhaps an idea would be to have it so that the bullets have a limited lifespan and don't quite reach the edge of the screen so the player has to get a bit closer to the target.
- Along the same lines maybe consider having the camera 'look ahead'. So depending on the direction the player is facing the camera will pan slightly more in that direction so the player can see with confidence how far away an enemy is
- In terms of movement I would have liked the ability to move backwards while shooting. I found myself a little too close to the enemies on a couple of occasions so when I had to move away I was turning my back to them, having to make that space and then turning back to finish shooting them
- You could easily make the level longer. It shouldn't affect the difficulty but would make it feel less claustrophobic and give the player a feeling of having more room to explore. Smoke and mirrors to make the place feel bigger!
- For vertical shooting maybe consider having a dedicated button that fires upwards. I found that I had to stop moving to shoot upwards which worked against me trying to avoid the enemies on the ground.
Overall a decent shooter which I enjoyed! When it comes to difficulty sometimes it's a fine line between making it harder to play and some things being frustrating for the player to do and denying them the ability to do certain things.
Hope this helps!
