Thanks for playing my game!
I can't say I'm surprised at my rank, I guess I've made it easy to one up myself next time. I do pride myself on putting fun first in all my endeavors.

My game had some major issues, and I appreciate everyone who made it through them and left a rating.
Inaccessibility. The base mechanics of the game are rocket jumping and bunny hopping. neither are explained in game, or on the game's page. I had hoped that by mentioning both techs on the thumbnail I would only draw people who already knew how to play, and that kinda worked! at least two of the commenters got times that clearly indicate use of movement tech.
There wasn't enough content. Even without movement tech the game's two levels could be completed in about a minute. The game's art assets could be counted on one hand, as I spent the majority of my time tuning the movement mechanics and making my first person controller feel more source-engine-ey. I am quite satisfied with the result but the average player probably didn't notice and I don't blame them. I also spent more time than I should have 'testing'.
The game kinda sucked. If you don't aim for a good time and just kill all the enemies and walk to the end, it's really easy. A lot of mechanics are not obvious, for example the railgun has no visual effect and the rocket launcher's smoke looks terrible and blocks vision. Enemy death sounds were broken and never played, which meant there was no feedback on kill other than the enemy vanishing. The first of the two levels was so basic it didn't really even count. Also the main mechanic of hybrid health/ammo wasn't really explored at all.
I've fixed a lot of this in my PostCompo update, available on Itch.

Despite all this, I am quite happy with my creation, and have had a lot of fun playing it, as well as all the games that I rated. I look forward to doing this again in October, maybe I'll break into the bottom 100!
