Boss battle with the tank upgrade was excellent! Even though I really sucked at it at first, it was so creatively done that I wanted to try again and again, because it was both fun and challenging! Other aspects were basic, but they worked for me. Really enjoyed the gameplay, combat, puzzles, everything! Very good entry!

The game is very nice! I really like how the tutorial is integrated directly into gameplay very clearly with visuals. I think this, along with other small details, is why the game feels balanced and smooth overall. One question I had while playing is how to deal with the monsters on the walls. Since the bullets are limited to three angles, I found it a bit difficult to aim accurately while also dodging. 

Very nice game I loved the design and the whole aesthetic. the bosses felt balanced and fun

Pretty fun game here, I really liked how the second boss requires you to juggle the locations of both yourself and the tank, which works especially well with its relatively simple attack pattern. I also appreciate the control popups when picking up the gun, tank, and double jump.

I only have a few suggestions / criticisms, but these are more nitpicks than anything and really didn’t detract from the experience:

• I wish there was a sound or more clear visual indicator on when the tank’s attack was fully charged. Judging when to let go is a bit difficult based purely on the line’s opacity.
• Also with the tank, I found that if it was within range to pick up while I was still controlling it, I was unable to press S to stand up until first moving the tank out of range.  This got me a couple times during the second boss.
• I’m not quite sure what the little potion-vial looking pickups did (if I were to guess, I think they upped my gun damage, but I’m not fully sure on that). A small indicator would be nice there.

I liked this game's design, and had fun! The only bug I found was I was able to start the first boss fight by double jumping under the room it was in. Overall very polished and a good experience :)
