I liked the game. It does a lot of things right, but there are some problems with it. So here's my review (I hope I'm not too harsh)
What I liked:
1. Nice looking visuals.
2. Nice enemy variety.
3. Story was simple but fun and to the point.
4. Level progression was decent.
Cutscenes didn't overstay their welcome.
What I didn't like:
1. The F ability (Scythe) is too Over powered. I could've beaten all 3 levels with that ability alone.
2. Sometimes it's hard to tell how much damage was dealt on an enemy. Sometimes an enemy would die from one hit by a certain attack, and then the same enemy type would die from more than one hit from the same attack.
3. There were some clipping issues in the scenery where certain buildings would get out of the camera frustum, which created a weird cutout effect.
4. The ability keys are a bit all over the place. It's hard to try and reach for J and K keys when the F key is much closer (and is triggers the strongest attack anyway).
Overall, great work and I look forward to seeing more of your work :)
