I like how it challenged me to play it again and again to see if I could reach higher upgrades. It is a simple, yet fun gameplay loop.
Some things I noticed while playing it:
- The enemy health scaling does not reset after you retry. I have to reload the game to reset it.
- In my first try I somehow managed to break the game: it started lagging and losing fps until I could barely see movement (might be due to too many enemy spawns)
Some suggestions:
- The orbital upgrade seems to be not that useful compared to other upgrades. An increased damage or insta-kill would encourage the player to time the orbits onto enemies more allowing for more strategizing.
- Probably has already pointed out but scaling is way too hard and progressing beyond two upgrades is really hard.
- Making enemies less spongy but increasing the amount of enemies you need to kill is more satisfying, since shooting 40 bullets into one enemy gets tiring.
- Some sounds would add a lot more juice
Overall, I weirdly like the simplistic design and enemy variety. The upgrades are interesting enough to encourage the player to get better at it. Keep cooking.
