Huh, that's the good example how the same idea could be realised in different ways! While in mine game you lose resource only upon killing an enemy, yours one takes it upon each attack. Excellent to be researched xD
So, the atmosphere is really nice touch - the lights, the palette - all was in handy to create right mood. Liked it. Gameplay is great paced, however, difficulty raises a bit too fast, as for me. Two kind of attacks with their own goal is pretty good idea too, however, it could be developed even further, I believe! For example, melee could be used for finishing wounded enemies, while shooting can debuff, for example.
Tutorial is very well done, that's a big plus.
Overall, very quality entry and a good basis for a further work. Thank you for this entry!
