I've just posted an update to the game that should have fixed the problems you were having. Thank you for your feedback!
Hi, the space bar button still makes the scrolling bar go down, but anyhow, I managed to get to the first boss, only to die :p
One thing to note: A message popped up after shooting the flies for a while about having collected a gold coin (didn't see any object that resembled such a thing during the game), only for the gold count to remain at zero, even when I was facing off with a boss, thus not letting me buy any health upgrades; also, when I last played the game (about 13-14 days ago), I had managed to get the Truly Pacifistic achievement, but after facing off with the boss today (my first time), the achievement disappeared :(
Other than that, it took a while to get used to 'pressing a direction button before pressing the Enter button to shoot in the desired direction' mechanic, but it was a good idea as it forces you to be careful where you move and makes you want to keep moving to avoid getting hit :D
I noticed, though, that my first few times of playing the game today was hampered by the slightly camouflaged spider (hardly distinguishable at times unless you keep moving, since the red eyes help a bit in this regard), so you might want the spider either brighter or ver dark as compared to it's background :p
Thank you for your extensive review! In light of that, I'm going to attempt to address each of your points with one of my own. Apologies if it's a bit long :)
One, I have incorporated multiple controls for shooting into the game. If one doesn't work, another might. Check the description or the in-game page labeled "controls" to find out what does what :)
Two, I have begun to encounter problems with some values behaving as they should in my downloadable test version and the same values not working in the online version. The gold value is one of these values. I'll look into how to fix it, although it may take more time than fixing the HP problem that arose before the patch.
However, I am also working on an update that should phase out the need for gold to upgrade your max health. :P
Three, the pacifist achievement tree has been bugging out to some major degree, and I had planned on maybe even getting rid of that achievement all together and replacing it with some more straight forward ones. For your information, the pacifist achievement tree was supposed to activate once you dodged flies without killing them for an extensive period of time (ten minutes to be exact)... yeah, I'm probably getting rid of that.
Three, I'm glad you thought that the movement/aiming system was a good piece of gameplay. I was considering replacing it with twin stick controls, but even if I do I believe I'll release an "original mode" or something along those lines with the original controls still intact.
Finally, if you got far enough in the game, you should have unlocked a few skins in the unlocks menu. Simply click on the word "Unlocks" in the main menu and select a skin, then play the game and the skin should show up. This should help make the spider more visible :)
Good luck, and thanks for the feedback!
P. S. good job getting to the boss with the gold system glitching, on one health it took me a few days to do!
No worries, I tend to write long responses (& dev logs) as well :)
1) Yes, I took note of that, and switched to using the Enter button for shooting soon after the Space button was misbehaving :D
2) Oh, I see. It seems that when I last wrote my reply, the spider can only survive 1 hit before being taken back to the main menu :p
3) He he, I too was wondering how on earth I had achieved such a feat, seeing that my spider never lasted more than a minute before getting hit by the flies D: ; nice touch on having the flies constantly heading towards you each time they spawn :)
4) Yes, it added quite a bit of challenge to the game, as compared to just spamming the Attack button and just steering clear out of harm's way :p
5) Hmm, I've never come across the Skins, even in the Unlock screen, and the only thing I would see is the unattainable/non-purchasable Health upgrade :(
P.S.S.: Heh, I didn't even realise there was a boss fight until it showed up, and then I forgot that I could shoot the bullets it was firing at me, leading to me 'dodging' into incoming fire :P XD . The gold glitch didn't affect me as I thought it was just a text display at the top right corner, seeing as the gold counter remained at zero throughout that one session (& the sessions that came after it) :p
