Can you somehow make upgrades more mandatory, without restricting game too much? I never really needed to upgrade anything besides cooling.
Bug, or maybe feature: While the ship cannot jump more than 2 squares high, you can drill up for as long as your cooling lasts.
Once you research something for the first time, you should be notified that you can craft more of this item inside cargo bay. People wont worry how to get more of some stuff or if the crafting is limited somehow. Or did I just miss the notification?
Craft even if you dont have all the requirements - if you do this, you could just keep all the blueprints inside research, while under storage you need just the following: tiny crystals, small metals, small lava, strange gloop, aberrant matter and obsidian. If you stumble upon large crystal, it would get disassembled into small ones immediately (this way capacity upgrade gets more mandatory).
Glitch in the game - save + quit clears area of zombies. So, if tons of them just drop out of the ceiling, simply press esc, save and exit the game, then continue from that save. No more zombies around. Also, give your companion the best weapon you have in your arsenal, as he will constantly have ammo you usually lack for anything decent.
There are plenty of bugs that make this game way less desirable than what it could be. It is also too simple, with only 2 moments in game where I had troubles. Spells that destroy all gems of one type are too powerful - put all 6 in the spellbook and you can have a nearly endless turn with some planning, while still dealing damage.
Psy - I get 12/23/18 for lvl1, so you can get 3 more points here. It might be possible to get //21, but it always gets stuck by 1 pixel or something similar.
Too easy - regardless what you build, you can easily win every level. Its not like you need to think and consider what to do on every level to beat it perfectly. Several cannons and one eye block and every enemy dies :) Yawn. 3/5
Hooah, managed to do all levels without a walkthrough :P Its a great game and quite challenging as well.
Do all levels have a single solution or are there some with multiple possibilities? (quite different possibilities I mean, not just trivial changes). Of course, those with moving stuff after activation excluded, these have many different options.
For the last battle, the easiest way of winning is to have your angel to tackle his. With some luck, you can place it in such a way your angel hits his, while enemy angel will not hit yours. Then, just get other units past him ( and destroy the castle (of course, you first need enemy angel to move in front of his castle).
Arrows could be written the other way round. I mean, they could start from bottom and then go up and turn left/right... like:

I
for the right one.
Otherwise, a very nice game.
